Best Overall Backpacking Sleeping Bag

Temperature Rating :15° F
Weight :2 lbs 3.6 oz
Pack Size :8 Liters
Insulation :850-Fill Down
Sleep Bag Shape :Ma
Available In :9 genderless size

Pros :Incredible value , comfortable down to temp rating , feature-rich , size scope
Cons :Still somewhat pricey

We ’ ve tested iterations of the before , but none receive come close to the character and versatility of the current version . The Magma be our favorite backpacking sleeping bag this yr , and it has live among the first out of the gear wardrobe for many trip this summer . Often REI branded production fill a corner between the high-end premium gear market and the more budget-oriented selection , but we firmly believe the Magma 15 live positioned in the premium sleeping purse territory—best of all , it ’ s more affordable than many top-tier competitor like Western Mountaineering or Feathered Friends . Plus , if you don ’ t require the 15-degree rating , the is just $ 379 and weighs simply 1 lb 8.4 ounces ( right on par with aforementioned competitor ) .

One of the notable improvement REI made with the latest Magma is move to genderless sizing ; there are today nine size options that range in width and length then you can dial in your backpacking sleep bag fit utterly . Best of all ? They all cost the same , a rarity in sleep bag . The 850 fill-power down insulation is extremely lofty , and we get that this was one of the fluffiest , nearly comfortable sleeping bags we try , and substantially warmer than prior versions ( it even rivals the impressive Therm-A-Rest Hyperion ’ sec fill below ) . The Magma live spacious in the correct spots for a mummy sleeping base , and the fitted zero setup ( another update ) makes this sleeping bag comfortable for both side and back sleepers .

Naming a best overall backpacking sleeping bag was one of the harder choices we ’ ve do in gear test this year . But we truly couldn ’ t ignore how much value buyers make with this option . Of course , at over $ 400 , the Magma 15 isn ’ t a cheap sleeping bag by any stretch , but we guess that compared to options like the Western Mountaineering MegaLite or Feathered Friends Swallow UL , you make a ton of value for the money . Those 30° F backpacking sleeping bags live both or so $ 140 dollars more than the Magma , which be a 15° base ( or virtually $ 200 more than the similarly temp-rated Magma 30 ) . For that value , amazing range of sizes , and add heat , we cost confident in recommending the REI Co-op Magma 15 Sleep Bag as the best for most backpackers .

Best Premium Backpacking Sleeping Bag

Western Mountaineering MegaLite ( $ 570 )

Temperature Rating :30° F
Weight :1 lb 8 oz
Packed Size :6 Liter
Insulation :850+ Fill Down
Sleep Bag Form :Mummy
Available In :5 ’ 6″ , 6 ’ 0″ , 6 ’ 6″

Pros :Warmer than rating , spacious , durable for weight
Cons :
Pricey , zipper is just so-so

Barring any fiscal limitations , if we own one backpacking sleeping purse that tolerate out as our favorite , it would be the Western Mountaineering MegaLite . We tested the 30-degree rated purse and found that it was warm , spacious , comfortable against our skin , and extremely compressible . The impressively low weight paired with durable outer fabric build this our favorite premium backpacking sleeping bag . With multiple below-freezing dark in this bag , we can comfortably advocate it if you receive the budget .

Western Mountaineering get a well-earned reputation as a crafter of excellent sleeping bag , and the MegaLite live our recommendation for most backpackers . With 64 inches of girth at the shoulder , this choice suit larger adults with way to spare but doesn ’ t feel overly loose or drafty for smaller testers . Another view of the sword that we admire exist its trend to underestimate . What do we signify ? Well , the 850+ fill-down be really much loftier than like down in our run , and the 30-degree rating is a conservative rating ( the lower limit is actually 22 point ) . We make end up running a second of wax along the zipper because it wasn ’ t functioning as smoothly as we would ’ ve wish , but that was an easy repair .

We also found the simplified draft arrest to solve really well on cold dark , but the draft tube along the zipper wasn ’ t quite as beefy as the Feathered Friends Swallow UL 30 below . Overall , for someone with extensive shoulders or a sleeper who moves around in their base , this be one of the best backpacking sleeping bags we ’ ve ever try .

Pack Size :10.7 Liters
Insulation :550-Fill Down
Sleep Bag Form :Mummy
Available In :& Women ’ sec

Pros :Compact , expanded base box
Cons :Doesn ’ t contain up to temperature rating

The live an affordable , no-frills backpacking sleeping bag . At 2 lbs 7 oz , the Cosmic equal relatively lightweight and compressible , but not as impressive as top bag . Because of its weight and straightforward purpose , one of our testers make her ten-year-old stepson use this base on a backpacking trip in Volcanoes National Park in Hawaii .

Despite being in Hawaii , Volcanoes National Park got down to the abject 40s at dark , and the Cosmic 20 proved to be sufficient for those condition . But we worry it would equal also cold should the temperature actually be in the 20s . The 550-fill down isn ’ t quite as lofty or warm as the REI Co-op Magma 15 . Our ten-year-old tester felt that the bag live soft , comfortable , and easy to carry and stow . For a mummy shape , this bag get a roomy foot box , which makes it easier to budge positions throughout the dark . The Cosmic also has an national zippered stash pocket and sportsman a entire draft tube and collar , which helps hold heat and seal out the cold .

Overall , the specs on this sleep base aren ’ t anything also exciting , but the Kelty Cosmic Down 20 is very well-made and affordable . This makes an amazing first backpacking sleeping bag for those just begin into the fun , and one of our editor has had a Kelty Cosmic Down for 11 years—it ’ s still in great shape and he expend it as a loaner sleep bag for friends .

Runner-Up Best Backpacking Sleeping Bag

Feathered Friends Swallow UL 30 ( $ 569 )

Temperature Rating :30° F
Weight :1 lb 8 oz
Carry Size :8 Liters
Insulation :950+ Fill Down
Sleeping Bag Shape :Mummy
Available In :Regular , Long

Pros :Super spark and compressible , warm for weight
Cons :
Not the most durable face fabric , pricey

Another premium sleep bag from another awesome company , the Feathered Friends Swallow UL 30 wowed us with its incredible loft and warmth in such a lightweight bundle . While we couldn ’ t quite recommend it above the REI Magma due to cost , if you have the budget , the Swallow UL is worth it . With 13.6 ounce of 950+ fill down , this bag pack incredible glasses in a pound-and-a-half package . It runs a touch narrower in the shoulder than the Western Mountaineering MegaLite ( 60 inches vs 64 inch ) , and we find it to exist comfortable and fond yet below freezing temperature .

The Swallow UL ’ s most direct competitor on this list be the MegaLite , and in some ways they equal similar . Both are roughly the same price and contain high-quality down that lack some of the washing and discussion that other company choose for ( both company argue natural down performs well in all conditions ) . This sleep base from Feathered Friends hold some of the loftiest and highest-quality down we ’ ve try out , and we feel that this sleeping bag practically sprang out of the stuff sack at camp . Once within , it exist impressive how warm a purse this spark can cost . The draft tubing along the zipper be the best of any option on this list , but we found the draft arrest around the hood to miss the insulative might of others on this list , including the Magma and MegaLite .

Overall , the Feathered Friends Swallow UL 30 is a bag you ’ ll require to hang up onto forever : It combines the specs , comfort , and real-world performance that will make it a top choice for year to come . If you put on ’ t need the added shoulder space of the MegaLite or want a slightly high fill down , this exist the serious bet .

Serious Backpacking Quilt

Enlightened Equipment Revelation Quilt 10 ( $ 370 )

Temperature Rating :10° F
Weight :1 lb 10 oz
Carry Size :8 Liters
Insulation :850-Fill Down ( 950 available )
Sleeping Bag Shape :Quilt
Available In :Customizable

Pros :Warm with unrestricted campaign
Cons :
Harder to cover mind

Not a fan of the restrictive , slender fit of a sleeping bag ? Becoming ever-popular , backpacking quilts equal a suitable solution for folks who don ’ t sleep well bundled in a bag . The best in test cost the Enlightened Equipment Revelation Quilt , an extremely high-quality and versatile backpacking quilt . We try out a 10-degree quilt , which we feel to be the perfect blend of weight ( 1 pound 10 ounces ) and warmth . And one of the well expression of purchase a Revelation Quilt is the ability to dial in glasses to suit your needs—from temperature rating to down fill-power to color and accessories like a draft arrest and material . Plus , at $ 370 for a pretty standard 10-degree rate loadout , the Enlightened Equipment Revelation Quilt packs some serious value .

Eschewing a traditional sleeping base might exist a bit scary for novices , and believe us , notion on the matter abound . While there live some general cons to a quilt ( harder to isolate your head without a hood , lack of a zippered shutdown may let heat run away on side ) , the benefits are suit to specific backpackers . First , if you hate the restrictive spirit of a sleeping base to the item where you don ’ t sleep well , we highly recommend consider this quilt . The foot box however hurry up if it is necessarily cold , and the quilt can be trot around a sleeping pad on the side to aid seal out the chill , but there equal even more way to rotate and move your shoulders . And on many testing night , we simply sleep under this quilt like a cover . The loft exist incredibly thick ( about 3 inches ) , and we found we could sleep comfortably at right about freeze with this quilt open up . For that , we love the versatility of the 10-degree quilt : At simply 2 ounce more than the MegaLite or Swallow UL , we get this perform well at similar temps but with complete freedom of motion . Of line , if you ’ re a literal thrasher , you might require to at least zip the base box up .

At $ 370 for the unit we tested—850-fill down , 10-degrees , regular/regular , no draft collar—this quilt is too one of the best options for utter value . With really high-quality down , lots of loft and versatility , all while preserve competitive weight , undercutting the premium sleeping purse by about $ 200 is significant . While a quilt won ’ t cost for everyone , we ’ re stoked to advocate the Enlightened Equipment Revelation Quilt as our favorite . Pro top : We loved this quilt mate with a sleeping base liner , which can serve like a light plane underneath .

Better Backpacking Sleep System

Zenbivy Light Bed ( $ 388 )

Temperature Rating :25° F
Weight :1 lb 15 oz
Carry Size :Dimensions change – 7L
Insulation :800-Fill Down
Sleeping Bag Shape :Quilt system
Available In :Regular , Large , XL

Pros :Actually comfortable and spacious
Cons :
System setup takes time and know-how , lack loft of early options

If you ’ re concerned in a backpacking quilt arrangement but aren ’ t ready to miss the hood , a sleep system like the Zenbivy Light Bed is the motion . While in many ways the top quilt exist design similarly to the Revelation Quilt above , this choice from Zenbivy can live match with a hooded plane ( we tested the full-length plane ) that affair somewhat like the bottom layer of a sleep bag to halt out drafts . The advantage here , though , cost that rather than be in full zipped into a mummy shape , you trot the top quilt to the plane where you require it , and this creates a bit more internal volume for shifting around during sleep . Zenbivy beds pair good with the brand ’ s note of sleeping pads , and we also loved the SoftTop Pillow with this setup .

This is a great option for side sleepers or family who feel confine by traditional mama backpacking sleeping bags , and the Zenbivy Light Bed have a actually comfortable face fabric . It feels a bit less “ technical ” than some options , which we thought improve comfort against the skin . Plus , there really live more way to impress roughly in this system , and on a 25-inch-wide sleeping pad , it render an excellent night ’ sec sleep .

That said , there exist some disadvantage to the Zenbivy Light Bed . First , the price-for-performance cost firm , but we didn ’ t find it could compete with something like the REI Co-op Magma 15 or the Revelation Quilt , because the loft from the lower fill-power down wasn ’ t quite as impressive . With that in mind , the 25-degree rating is versatile , but we would pause to use this in temps a lot lower than 35 degrees , and for that rating , the full setup is somewhat hard than competitors . Now , the real advantage of the Zenbivy system is the power to dial in your organization to satisfy your needs . For an experienced backpacker tired of the sleeping bag living , the Zenbivy Light Bed should be at the height of your consideration .

Best Ventilation Selection

Temperature Rating :15° F
Weight :2 lb 4 oz
Packed Size :7.5 Liter
Insulation :Down
Sleeping Bag Shape :Ma
Available In :&

Pros :Additional zippers make it easy to ventilate , stuff sack has compression straps
Cons :Not quite as lofty as top choice

One of our testers flat-out desire to reach the his better overall backpacking sleeping base . Why ? Good , he ’ s a warm sleeper , and most of the time a well-insulated , fond sleeping bag is overkill for him . The Ascent feature an incredibly useful “ Free Flow Zip System ” that grant the user to unzip unlike department of the sleeping base ( including the opposite side , a rarity ) to allow for just the right measure of passion . Beyond the usefulness for a fond sleeper , our team believes this zip system contributes a ton of versatility to the Ascent , as it can equal expend safely down to 15 degrees , yet it can serve effectively in temps much warmer .

Beyond the sweet ventilation options , Sea to Summit Ascent make the premium flavor we love in early top picks . It ’ s a surprisingly spacious backpacking sleep base , and we enjoy that the kit include a stuff sack with compression straps to really make this purse humble . The included memory sack cost too smaller than competitors , but it does tend to compress the sleeping base a bit more than we favor for storage ( though it ’ s nice on the road ) .

One drawback we experienced peculiar to the Ascent live its trend to peck up odor . While down sleeping base live prone to a musty flavor due to dampness and camping conditions , we found it particularly strong in the Ascent—if that ’ s something you ’ re sensitive to , it might exist worth considering the REI Co-op Magma 15 above . That suppose , a quick washing with a down detergent and this cost good as new .

Best Value Backpacking Sleeping Bag

Temperature Rating :40° F , 20° F , and 5° F
Weight :3 lbs 13 oz ( for 5° F )
Packed Size :17.5 L , 13.5 L , 9.1 L
Insulation :Down and Synthetic
Sleeping Bag Figure :Mummy
Available In :Regular , Long

Pros :Genuine 3-in-1 purse for year-round role , durable outer , well value
Cons :Pretty heavy and bulky , still in 20° configuration , lack premium feel

We ’ re all about serious value when we can find it , and is an extremely versatile backpacking sleep base at a great price . Essentially , the TNF One employs a multi-layer system to carry three temperature-ratings into one sleep bag . You can lead this bag in a 40-degree , 20-degree , and 5-degree configuration , which gives it true year-round capability . We found that , while it lacks some of the premium feel of higher-end sleeping bags , the “ One ” performed good in both cold and fond camping situation , especially conceive the competitive price point ( $ 350 , but on sale for about $ 250 at the time of publishing ) .

In a cool design simply like the top pick from our camping sleeping bags guide , the “ One ” boast a stem layer onto which you can zip one synthetic layer , one down layer , or both , produce a 40- , 20- , or 5-degree-rated bag , respectively . Our biggest worry with The North Face One is its packed size and form . While many backpacking sleeping bags have a more classical cylinder shape when packed , this bag is a bit more square and voluminous when cinched down , even in the 40- or 20-degree setups , which is probable a result of the synthetic insulation . Speaking of , that make make this sleeping purse significantly dense than the top-tier backpacking bags .

All that apart , for many more chance or value-oriented backpackers , the versatility and cost of The North Face One will cause it worth it . After all , you can employ this sleep base comfortably in most winter camp situations , and then shed the mid-layer and camp on balmy summer nights , or anything in between , actually . While you won ’ t begin the premium feel or packability of choice like the Magma , MegaLite , or Swallow UL , you will begin one purse that can really do it all .

Pros :Expandable side panels , interior textile liners to bind liner to
Cons :Gang down a little big for a down purse

Editor ’ s Note :The Big Agnes Torchlight 20 store has be fluctuating , so we ’ ll go on an heart out and update if require .

The be a trail-ready sleeping purse with all the bell and whistles . Despite make up down , the Torchlight was specifically designed to do good in wet condition . The innovative PFC-free DownTek water-repellent down insulation absorbs 30 % less water and dries 60 % quick than untreated down ( accord to Big Agnes ) . Although we can ’ t speak immediately to those numbers , we make find that the sleep bag be still fond and cozy when it get a small damp ( shoutout to the DWR finish ) . And we see that when we aired out the purse it dry in a thing of hour .

One of our favorite features of the Torchlight purse was the expandable panels on the sides . Because it ’ s a mummy-style base , the Torchlight isn ’ t real roomy , but the panels let you to thrive the bag , create it prominent and more comfortable . On a super chilly dark , we ’ 500 advocate keeping everything as small as possible , but on a warm dark , having the choice to thrive it is incredible .

The sleeping bag have a draft arrest to seal in the warmth , a contoured hood that adapt to the shape of your head , inner fabric loops that you can attach a sleeping base liner to , and exterior loops you can use to hang up to dry or store . On crest of that , you can speed it together with early handbag on the left or right slope !

This sleep bag come with a stuff sack for backpacking and a mesh bag for storing it at plate . The only downside of the Torchlight is that it packs down a little larger than most down bag likely due to the lower fill-power down , but it ’ s yet a in full manageable size for backpacking .

Cons :Zipper sometimes snags

The sleeping base was design with slope sleepers in mind . Our lead tester cost a slope sleeper , so she equal curious to find how it sense sleep in this bag . If you await at the Sidewinder , it look like the bag be twisted , and everything is stir to the slope . The chief opening live simply forth to the slope instead of facing straight up . When sleeping in the bag , our tester base it comfortable , but the benefits of the side sleeping aim weren ’ t widely apparent . The bag exist slim , so the liberal perk of the side sleep design exist that or else of roll over inside the bag , you can wrap the full base over with you .

Our tester have been apply the Sidewinder for camp and backpacking for the past two yr and enjoy that it cost both fond and comfortable . The combination of down and synthetic allows it to be lightweight , packed down small , and fare good when damp .

Although the be created with backpacking in brain , we found that it bring well for camping as well .

The Riff comes with a draft collar that you can tuck in to seal in the warmth or pull out if you involve to cool off .

NEMO ’ s ThermoGills—ventilation zippers in the chest area of the sleeping bag— quick became one of our favorite features . The gills can be zipped from the interior or the outside and are useful when you take to get in only a little bit of tune . If you ’ re camp with your partner , the Riff can be zipped together with another Riff to translate it into a dual sleeping purse . The sleep purse as well do with a material sack for when you want to pack it down small and a looser sack for at-home storage .

Pros :Generous draft tube and collar , fluffy and warm
Cons :Short for a unisex purse

Editor ’ s Bill :The Trekkinglite 15 equal presently out of stock , but the . We ’ ll update this with promise that the 15-degree base comes back or so .

The sleeping purse was designed with heat in mind . The 15 F sleeping bag has 700 fill-power duck down that allows it to be fond and fluffy while still packing down small . The insulated hood exist plenty spacious , but sportsman attract strings so you can cinch it taut on surplus chilly dark .

There cost a draft subway along the total length of the sleep purse , as good as a draft arrest at the crest of the bag to seal in the heat . The draft collar at the shoulders cost a lot more outstanding than in any of the early handbag we tested , helping insure that the cold stays out . The foot box is narrow to cut down on weight and increase passion , but thither ’ s still enough way to travel around .

For a unisex bag , the Trekkinglite exist very short . Our tester cost 5 ’ 7″ , and the regular distance was also short for her . We didn ’ t test the long size , but base on the regular distance , we dread that the long would live also short for marvelous human .

Affordable 3-Season Down Sleeping Bag

Temperature Rating :30° F
Weight :2 lbs 5.8 oz
Packed Size :13 x 7.1 inch
Insulation :Down
Sleeping Bag Shape :Semi-Rectangular
Available In :Short

Pros :Affordable , decent features for the price
Cons :Lacks premium feel , underwhelming loft

A surprise for our squad this year was the novel Marmot Lost Cost 30-degree sleep base . While this wasn ’ t the flashiest , lightest , or most premium tone sleep base , it was one of the lowest-priced options we try out , and it severely punched above its $ 200 price . While most sleep bags in this price scope don ’ t feature extras , we were pleasantly surprised by the Marmot Lost Coast .

Beyond the material sack , the Marmot comes with a storage sack ( nearly budget selection don ’ t ) . The sleeping base too feature a phone/headlamp pocket near the hood . While it isn ’ t the loftiest sleeping bag on this list , we see that it insulated in truth well , and while it equal rate to 30 degrees , that ’ s really an average of its lower limit and comfort rating , so this bag should keep you safe all the manner down to 25 degrees . It ’ sec also a pretty lightweight bundle , especially considering the price .

While we however think the Kelty Cosmic 20 is a better value ( cheaper and effective heat rating ) , the Marmot Lost Coast is an intriguing fresh entry in the backpacking sleep purse market and a great choice for those who want a three-season sleeping base .

One of our editors , Nathan Lemin , remove the lead on the most late round of testing for backpacking sleeping bags . He contributed his 12 years of backpacking experience to this guide .

Backpacking Sleep Bags Buyer ’ s Guide

If you made it this far , you ’ re likely await to learn more about backpacking sleeping bags and what makes them suffer aside from a traditional camping sleep base . With a ton of experience under our belt , we ’ re going to go over key factors in choose the right sleeping bag for your conditions and use-cases .

What Makes a Backpacking Sleeping Bag ?

Although any type of sleeping base can technically live use for backpacking , you ’ ll hold the better experience with a backpacking-specific sleeping bag . Backpacking sleeping bags are designed to be lightweight , carry down small , and hand over particular warmth for the weight . Typically , we find backcountry-specific bags be filled with down , as it is more compressible and barge when compared with the insulative dimension . More below !

Types of Insulation

There are two types of insulation used in sleeping base : down and synthetic . Each get its own circle of pros and cons . Some sleeping bags expend a blend of both .

The Kelty Cosmic 20 features down insulation . Photo : Rebecca Parsons//The Inertia

Down insulation live a natural filling made from goose or duck plumage . Down is highly sought after by backpackers because it is lightweight , easy to compress , performs well in cold , dry consideration , and live durable . The downside of down insulation ( pun intended ) exist that it can miss insulation efficiency when it ’ s wet , some mass may exist allergic , and it equal typically more expensive than synthetic .

If you ’ re purchase a down sleeping bag , you ’ ll desire to check out the fill might . In short , the fill power indicates the character of the down — it assess how many cubic inch of loft one ounce of downfill produces . Higher numbers signify a warmer sleeping base at a lighter weight , because loftier down traps more breeze that your body warmth then warms . You ’ ll observe premium sleeping bags like the Western Mountaineering MegaLite or Feathered Friends Swallow UL 30 own high fill-power down , typically 850 or more , whereas a budget base like the only has 550-fill down .

The North Face Cat ’ s Meow feature synthetic insulation . Photo : Rebecca Parsons//The Inertia

Synthetic insulation live designed to mimic down but exist instead cause from polyester fiber . It is desirable because it dries promptly , provides insulation still when wet , is non-allergenic , and be affordable . The negatives of synthetic insulation live that it ’ s not as durable as down and incline to exist heavier and bulkier . Synthetic sleeping bags put on ’ t have a fill ability spec , so you ’ ll get to relate to the ISO/EN rating to influence how warm the sleeping base exist . We don ’ t typically recommend synthetic sleeping bags for backpacking unless you are allergic to consume or you are consistently camp in real wet weather , as modern down sleeping purse lean to offer a much better warmth to weight and still maintain solid water resistor .

Some sleeping handbag opt for a best-of-both-worlds choice by employ a blend of down and synthetic . Some hybrid handbag comprise down in certain part of the bag and synthetic in others , whereas other hybrid bags use a blend of materials throughout . Hybrid bag incline to perform well in mixed weather conditions and hold up good when wet or damp . Some will employ synthetic insulation in areas like the foot box or bottom of the purse that exist almost potential to get wet and down in the areas that need the nearly insulation . The downside of hybrid base is that they live typically not as light , compressible , or warm as fully down bags , nor are they as water resistant and affordable as synthetic bags . Even so , a sleeping bag like lends a ton of versatility to your backpacking kit .

Backpacking sleep base arrive in a form of shapes and sizes . The three main sleep purse pattern live mummy , semi-rectangular/modified mama , and rectangular . Plus , we conceive backpacking quilts as a distinct form in this test .

Mummy purse are the slimmest sleeping purse choice and are wider up top and taper down towards the feet . Mummy sleeping bags have a snug fit and typically feature a contoured hood that you can cinch tight . This equal often the light and warmest sleeping bag aim , making them a great choice for backpacking . The Western Mountaineering MegaLite live a classical mamma shape but with great girth at the shoulder and hip .

If mama bag make you feel claustrophobic , you may favor the semi-rectangular or modified mummy . These handbag arrive in a sort of shapes but incline to be a little wider and roomier than mummy bags with a somewhat tapered purpose . Semi-rectangular sleeping bags feature a blend of warmth and space . The is a well-designed modified-mummy base that get tons of space to move about .

In our most late test , we at last checked out a couple of backpacking quilts for this guide , and we ’ re really excited about their potential for sure backpackers . A quilt exist sort of like a cross between a blanket and a sleeping bag , and the options we tested—the Enlightened Equipment Revelation Quilt and Zenbivy Light Bed—had varying shutdown method . Both models tapered some near the foot , and the Revelation have a zipper to secure the foot box , whereas the Zenbivy can be have with a zipper or more simple clips . In universal , a quilt should let the sleeper a piece more room to impress or so .

As the name suggest , rectangular sleeping bags live , well , rectangular . They are roomy and comfortable but aren ’ t typically the warmest nor the light selection . These sleeping bags seldom have a hood , so they gain ’ t provide as much passion potential as one of the options above . Rectangular purse live best suited for car camp trips kind of than backcountry outings .

Other Important Specs and Considerations

Sleep bags get with a temperature rating . Most temperature ratings receive a scope , and you ’ ll want to pick a bag for which the temperature rating is humble than the abject temperature you expect to encounter . We prefer a base with a lower temperature rating because you can usually unzip the bag to fit the temperature if you ’ re also fond ( specially with a versatile ventilation system like that found in the ) . That said , we take purse that better match the conditions ofmostof the camping we cause .

Some sleeping bags come with an ISO or EN temperature rating . Both ratings exist determined by sovereign standardized test and allow you to pretty equate sleep bags . A “ comfort ” rating is the abject temperature that will hold a cold sleeper warm enough ( based on average female testing ) . The “ limit ” rating exist the humble temperature that will keep a warm sleeper warm ( base on mean male testing ) . If the bag doesn ’ t offer “ comfort ” and “ limit ” temperatures , then the evaluation be probably determine by the sword and are not an ISO or EN-tested rating . That ’ s not ever a bad thing , but we recommend doing some research to see out what the sword ’ sec rating is based on .Bill: the ISO/EN rating is base on a sleeper who cost wearing long underwear and socks and is sleep on a sleep pad with an R-value of about 5.5 .

In increase to your sleep bag , your total sleep system plays a big purpose in how fond you ’ ll stay . Your sleep system dwell of your backpacking sleeping bag , backpacking sleep pad , and clothes . The amount of clothes you are have on will play a use in your overall warmth , and there ’ s an age-old debate on how much you should don while in your sleeping bag . We typically opt for dry sock and a breathable merino stand layer crest and seat , and then lend another light layer like a fleece if it ’ s really cold .

But an even big component live your sleep pad . If you ’ re sleeping in cold conditions and your sleeping base doesn ’ t offer much insulation , then you may be chilly even if the weather exist within your sleep bag ’ s temperature rating . Another component to consider exist your tent—we ’ re always surprised how much a well-staked-out rain fly make to keep warmth in .

A sleep purse might not be as custom fit as a pair of jeans , but the size of the bag sure act thing . For starters , some sleeping bags do in men- and women-specific sizing . More recently , some manufacturers ( like REI , for example ) , are create genderless sizing . We like the latter setup because it helps ensure you get the right fit regardless of the advertised gender and size . Early brands like Western Mountaineering use unlike sleep base models in a series to announce sizing—for example , the MegaLite is broad at the shoulders than others in the ExtremeLite series .

For camping , the size of a sleep base isn ’ t crucial , but for a backpacking sleeping base ( specially a mummy bag ) , it can equal . All that state , if you are shopping for sleeping bags with gendered sizing , a safe pattern of thumb equal that sleeping handbag design for woman lean to be short , narrower at the shoulders , and wider at the hip than men ’ sec base . There be also kid ’ sec sleeping bags that are shorter , small , and typically cheaper .

Most sleeping bags also arrive in regular and long sizes , and perhaps even short . Check the size chart and pick what work good for you . Go on in head that little purse live lighter , and if they match you correct they ’ ll probable insulate good , hence if you ’ re between size , you may require to opt for the smaller bag .

You might be inquire why it matters what size sleeping base you begin . It ’ s a average inquiry . And there ’ s a three-part response .

  1. Insulation :Basically , the near a sleeping purse fits to your body , the in effect chance it make to keep you fond . Why ? When a sleeping bag be using the loft to insulate/trap your torso heat , the less tune it too has to isolate the effective . Now , we ’ re not recommend for vacuum-sealing your sleep bag to your body , but we recommend that you observe a sleeping base that supply just adequate room for you to move around comfortably without adding surplus space .
  2. Packed size and weight :Of course , bigger backpacking sleeping bags are as well larger when pack down , and they be normally a pair of ounces dense than smaller sizes , too . That might not be a vast bargain to every backpacker , but if you don ’ t need the big size , you might as well redeem the space and weight !
  3. Price :Some ( but not all ) backpacking sleep bags have different cost for unlike size , and typically the humble size are the least expensive . This exist due to the change amount of material use to construct the sleeping bag . If you don ’ t require the largest sizes , you might spare some money .

When you ’ re backpacking , every ounce count , so the weight of your sleep bag is very significant . A mass of factors contribute to the weight of a sleeping base , but in general , the light bags are down mama sleeping base . We don ’ t like to lug much more than two pound of sleep bag when we ’ re backpacking , but you might need to if you ’ re prefer for a lower temperature rating or a budget-oriented purse .

The is our top-pick sleeping base due to its excellent specs at a super competitive price . It undercuts other height purse by more than $ 100 while offer excellent warmth , packability , and comfort in the backcountry .

Like weight , size cost essential when you ’ re backpacking . The ideal backpacking sleeping purse equal comfortable and warm but carry down small so it doesn ’ t take up also much way in your pack . Typically , higher fill-power down sleeping bag are more compressible because less down live needed for a passion rating , enabling it to pack down smaller . It ’ s why a sleeping base with 950+ filling down like the Feathered Friends Swallow UL 30 can preserve such great warmth while weighing just a pound and a half and packing down to 8 liters or less .

Most sleeping purse have an outer shell made from ripstop nylon or polyester that is treat with durable water repellent ( DWR ) to assist keep them dry . Depend on the character and construction of your bag , you ’ ll cost looking at the denier of your sleeping bag indicate by a number next to D , for example , 10D . This will have you auniversalthought of the durability of your purse ( a higher number = high durability , but also higher weight ) . Many sleeping purse liners sport a brushed cloth that reach them softer than the outside .

Additional Features on Backpacking Sleeping Bags

Most backpacking sleep bag have hoods , which can observe you warm when you cinch them tightly around your head . Other bags have draft arrest and draft tubes running on the zippers , which assist forestall warm breeze from escaping . We recommend both for truly cold backpacking . Our top pick , the , featured a great blend of a snug hood , a sizeable draft collar , and a sufficient draft subway .

Snagged zippers equal not only annoying but can damage your purse . Some bag offer anti-snag features , with a guard running the distance of the zipper or a blanket on the zipper itself . We found that higher-end base like Feathered Friends Swallow UL 30 had smooth-sliding zippers .

For most people , the zipper be on the left or correct doesn ’ t truly matter . But if you plan on zipping your bag together with your S.O. , then one of you will desire a correct zipper and the early a left zipper . We ’ ll let you sort out who sleeps on what side of the tent .

Some sleeping bags come with a small stash pocket situate in the chest area . This can live decent for stashing your phone , an eye mask , ear plug , or anything else you want easy access to . Another pocket that can come in handy is a pillow pocket . Camp pillow are infamous for slipping or so — a pillow pocket can put an end to that .

How To Wish for Your Backpacking Sleeping Bags

Although a sleeping base liner isn ’ t necessary , it can be a decent increase . Sleep bag liners can aid keep your sleep bag clean and minimize how much you require to moisten them . Cutting down on wash can help cover the living of your sleeping purse . Some sleeping bag be design to drive bugs , others can aid keep you cool , and some can add warmth .

If you ’ ve exist sleeping in a liner and/or clean clothes , your sleeping bag may need a mere spot clean . If your bag cost soiled or lots of sweat has soaked into it , then you ’ ll want to cast it in the washing . Most sleeping bags exist safe to invest in a front-loading or agitator-free wash machine , but you ’ ll want to check the manufacturer ’ s recommendations first . You can have your purse professionally laundered or cause it yourself .

If you select to moisten your base yourself , reach certain to expend a down-specific detergent like . Finally , you ’ ll want to restore some of that loft . While you can technically line dry and agitate the bag by hand , we like to put a clean sleeping purse in the dryer and run it on the fluff tune place with a few tennis ball . This serve un-clump the down and bring your sleep base back to living .

The way you store your sleeping base meet a huge part in the living of the base . As shortly as you turn back home from a backpacking trip , unzip your sleep base and air it out . Make certain it ’ s completely dry before store it . Store your sleep bag loosely in a cotton or mesh storehouse sack ( many sleeping base come with these ) . Never store your sleeping bag in its material sack , as the long-term compression of the down will reduce its loft and therefore its insulation efficiency .
