The Mountain Hardwear Bishop Pass ($285) earns its place on the podium as our best budget down bag thanks to its versatility and wallet-friendly price tag. This bag is available in 0°F, 15°F, and 30°F variations. After testing the middle of the pack option for more than a year, we found it delivers ample insulation, a decent packed size and weight, and sturdy materials at a very reasonable price.

It’s 650 fill-down lofts to 5.5 inches and is protected by a DWR (durable water-repellent) ripstop nylon shell. The 20-denier shell holds up well to abuse, and the 30-denier liner is soft against the skin. At 2.25 pounds, this bag is an average weight for its class.

We also loved that it can be zipped together with other MHW bags, featuring an opposite-side zipper, to create a larger shared bed for two. While this bag might not be the warmest or lightest in the lineup, it is more durable than some of its thin-skinned competitors. The materials are a bit sturdier, which does keep this bag above two pounds.

One minor complaint is that we prefer a bigger, circumferential draft tube at the neck (like those on the Mountain Hardwear Phantom or Western Mountaineering AlpinLite), but the collar baffle does a decent job of keeping cold air out. Also, it doesn’t pack as small as other bags with higher down fill power, but for the price, it’s acceptable.

As a mummy-shaped bag, the Bishop Pass will be more thermally efficient than roomier bags, but if you know you’re liable to toss and turn, consider a spoon-shaped bag like the NEMO Disco. You’ll only need to shell out $30-40 more for it, and the interior space makes it a crossover-worthy bag that can go backpacking and camping. This bag also isn’t quite the bottom dollar on down sleeping bags, and the $170 Kelty Cosmic Down will get you through similar temperatures, just with a lesser quality down and shell fabrics.

If you’re on a budget but still looking for a bag that performs well, the Bishop Pass checks all the boxes without compromising too much on quality. It’s a great choice for folks who want the warmth and packability of a down sleeping bag without the high price tag of top-tier models.

Made for hikers of all sizes, the newer-to-the-scene REI Co-op Trailmade Bags ($119) offer an impressive six different sizes made to fit anyone, regardless of labels. But even beyond the accommodating fit, the price is the big draw here, and for a little more than a Benjamin, you get a highly serviceable camp bag that’ll stick around for the long haul.

During our inaugural camping trip with this bag in Joshua Tree National Park during spring, we tested the Regular size and found it ideal for our 5’10”, 165-pound tester, and kept us warm down to 32 degrees F. The footbox was a surprising highlight of this relaxed mummy-cut bag, which sports a roomy ‘up-kick’ of space and allows for full extension of your tootsies without cold spots — very nice. The taper through the legs is a bit narrow, however, so those who aren’t used to the mummy cut might find the slumber a bit snug.

The Trailmade is currently only offered in a 20-degree temperature rating (that’s a comfort rating of ~31 degrees F), which, through our testing, we found that most sleepers found accurate, save for some of the colder sleepers who generally don’t find synthetic bags as warm. We would love to see an additional warmer-temperature summer bag for our mid-season excursions. 

The insulating properties of the recycled polyester fill aren’t anything to rave about, but it does its job admirably in this cut and provides a predictable amount of warmth. Additional niceties on the Trailmade include a snag-free zipper guide, as well as a stash pocket on the exterior of the bag for your phone, headlamp, or water filter. The exterior fabrics follow the same ‘heavier-but-durable’ ethos, and after two seasons of use now, are still holding up excellently.

Perfect for those who want to fine-tune their sleeping bag fit or just get outside without sacrificing the gas to get there, the Trailmade 20 has been a welcome addition to our gear closets and is a bag that’ll serve many in their introduction to the outdoors.

With 60 inches of shoulder girth and venting options for when things get too toasty, the NEMO Disco ($300) is one of our favorite bags for active sleepers. The ample room is complemented by two of NEMO’s Thermo-Gill vents that zip open to allow for more space in the torso. Zip them shut on especially cold nights to keep more heat in and lessen the dead air space.

It’s that ‘spoon’ shape that really won us over, however, and for those with wider hips, it can be a game-changer. While the middle of this bag tapers a bit (to keep some thermal performance around your core), the footbox expands out to nearly the same width as the shoulders and allows for a number of different sleeping positions.

The 30-denier ripstop shell feels sturdy and held up well in testing on rough terrain. The nylon liner is also super soft and pleasant to sleep against. A final touch we appreciated is the breathable, waterproof foot. Down loses its warming power when wet, and our feet are the first place to get saturated from condensation in the tent. It also touts one of our favorite bonuses: it comes with a compression sack.

Heavier fabric and plenty of fill mean that the 15-degree Disco we tested weighs in at a hefty 3 pounds, 5 ounces in the regular. This is still way lighter than a lot of bags, but a full pound more than some of the ultralight bags tested.

If you’re after a bag that doesn’t short-sheet you but still trims the fat a bit, consider some backpacking quilt options, such as the Katabatic Alsek or Enlightened Equipment Enigma, which both provide impressive room to move around in.

If you sleep on your side and dislike sleeping on your back, try the Disco — we prefer the 30-degree version for summer use and the 15-degree version for shoulder season backpacking. This bag is well-suited to those who need to dial in their temperature throughout the evening or who need some extra room to stretch out or move around.

Backpacking quilts are a whole other ballgame compared to sleeping bags, and while there are a vast number available, we’ve settled on the Katabatic Alsek 22 Quilt ($389-509) as the best out there for most folks.

Besides the packed volume and weight benefits of going with a quilt (on average 20-30% lighter), the versatility of open-backed camping insulation is huge. We initially tested this quilt on a late-season hike of the PCT Section J, where temperatures swung widely. Thankfully, the Alsek is amenable and handled everything from sub-30 to balmy 55-degree temps overnight.

The Alsek’s pad-attachment system is the best we’ve used. It consists of 2mm cords that encircle your sleeping pad and attach to the quilt in four different spots. These can be snugged in to close or widened to provide more ventilation. Add an elastic binding on that back opening that keeps drafts at bay, and we’ve been cozy all night in this quilt.

Compared to standard bearers like the Enlightened Equipment Revelation (which we’ve previously awarded), we found the finish on the Katabatic line of quilts to be a cut above, with high-end Pertex fabrics being used. Also, while the temp ratings of EE quilts are a bit optimistic for some campers, the Alsek swings in the opposite direction and can often be taken down to its rating.

While the Alsek isn’t able to be fully unzipped, we found that we lost less heat from its foot box compared to quilts that do turn into blankets. So you’ll trade some versatility, but for taking the quilt right down to the limit, we found it a worthy compromise.

It’s also still quite easy to pop a leg or two out overnight if things warm up too much, and for those after the full blanket experience, Katabatic also makes its Flex line of bags, which open up entirely. Or, look to the Feathered Friends Flicker UL Quilt, which sports a full-length zipper and is just as on-the-money when it comes to temperature comfort rating.

Price is the trade here, but starting at $389 (for a 5’6″ length and 850 fill down), this quilt isn’t unobtainable, or even expensive compared to some 20-degree sleeping bags. With the ability to dial in your perfect quilt (six different sizes are available and two down types), we think the Alsek 22 Quilt is an excellent option for lightweight hikers.

The Mountain Hardwear Phantom ($510-740) borrows fabric from the brand’s legendary wisp of a down jacket, the Ghost Whisperer, and generally turns the dials in a bit more to create an even more fine-tuned sleeping bag for those headed into the alpine. Other notable updates include the pivot from a 20D nylon taffeta to a more premium (and lighter) 15D ripstop, as well as an even lighter weight.

The tradeoff to a lighter fabric set throughout seems to have worked, as even though the bag pivots to a slightly lesser 800-fill goose down (the previous version was 850), it is no heavier for it and still achieves the same comfort and temperature ratings. The climbers and mountaineers among us flocked to the 0-degree version ($710) of this bag during testing, and after returning from far-flung exploits, they provided a unanimous “yea.”

We’ve also now tested the 15-degree version of the Phantom ($610) on a backcountry mission to paddle two different Arctic rivers this summer and found it to be a version that’s primed for 3-season adventures, where weight still matters. There is a 10-ounce difference in fill weight, which makes the lighter version ideal for temperatures that frequently dip below freezing.

The large foot box and 58 inches of shoulder girth allow for comfortable sleeping, with enough room to stuff a hot Nalgene at your feet to keep your toes warm. We found the 10-denier nylon fabric is tougher than most bags in its class. On cold nights, 6 inches of down and large baffles keep the draft and cold air out.

We really liked that the neck baffle encircles the entire circumference of the bag, offering protection to keep your body heat sealed in. This bag is offered in short, regular, long, and left or right zip. It also comes with its own compression sack.

Unfortunately, all of this bag’s warmth comes at a high price. Our biggest complaint is that it is not in the budget for many shoppers, but that’s the price you pay for a hyper-specialized bag. A similarly specced option (with a more palatable price) is the REI Co-op Magma, which we’d recommend to folks that the Phantom appeals to but don’t have any big mountain needs.

Overall, the Phantom is a must for any serious climber or winter backpacker looking for a lightweight adventure bag that doesn’t skimp on warmth or quality. The Western Mountaineering AlpinLite is the logical upgrade from this bag for those looking to spend more on a true investment piece, but we think the Phantom does the job just as well for less out of pocket.

Newly revamped in 2024, the REI Co-op Magma ($349-399) is back in a big way, having been totally rebuilt from the ground up and designed to offer 9 (!) total sizing combinations. From Short and Narrow to Long and Wide, REI has also ditched the standard gendered convention to get more people in better-fitting sleeping bags, and our side-by-side testing shows that it’s working.

Thankfully, REI retained all that we loved about the previous version of the Magma: the 850-fill power down, the lightweight 15-denier Pertex nylon shell, and excellent packability are all still standouts, but those added sizings are what really won us over in the new version. We put in evenings in the Medium-Medium and Medium-Long cuts and found them to be sized perfectly.

Abandoning the traditional gendered style of sizing sleeping bags may be a little confusing for some, which is why we highly recommend trying out the Magma in person before making a purchase. To be sure, the Magma is still a mummy bag through and through, which makes it ideal for backpacking; however, accurate sizing is still crucial for a proper fit. Thankfully, an ample vaulted foot box ensures plenty of room for your feet.

One of our bigger gripes with the previous iteration of this 15-degree sleeping bag was a decided lack of warmth for such a rated bag, but no longer. REI added an average of 7 extra ounces of down across the size range, and this is now a toasty warm bag. Now, if they can overhaul the included stuff sack (which, unfortunately, lacks has compression system), we’ll be set.

The mummy-cut Magma is pretty comparable to the Therm-a-Rest Parsec, but we found that bag to have a more generous cut through the legs, which won over those of us who toss and turn in the night. When you’re checking out the Magma in-store to dial in your fit, make sure that the snug profile is to your liking.

If finding the perfect fitting sleeping bag has you tossing and turning, the Magma offers up a new way. With a recently boosted warmth, trim backpacking mummy cut, and overall light weight, this bag has backpacking chops, and it doesn’t ask you to cram yourself into it to take advantage.

The Western Mountaineering AlpinLite 20 ($685-730) is built to mimic everything fans loved about its UltraLite bag but with the addition of extra shoulder room. Indeed, the size long offers up to 65 inches of shoulder girth, affording a few extra inches over most of the competition at a similar weight — and all trimmed out in some of the nicest materials you can get your hands on.

The brand designed the 12D shell fabric to be extra breathable, promoting as much loft as possible from the 1 pound 3 ounces of 850 goose down (that’s 5 ounces more than the Feathered Friends Hummingbird 20, for those counting). The result is a finely tuned bag that is super warm and is backed up with a jumbo, 3D-insulated collar that helps seal in as much heat as possible for alpinists and serious backpackers.

The larger-than-normal cut is also a step above most ultralight bags, and can accommodate tucking in some clothes or a warm water bottle beside you. We found that this extra space also makes this bag a bit more versatile when it comes to venting, as you’ve got a bit more room to move around in when you’ve got the zippers pulled down.

This is one of the most expensive bags on our list, but it deserves consideration for those committed to quality. The high loft and down rating may well justify this expense for some, and like Feathered Friends’ sleeping bags, it should be considered an investment from a boutique gear manufacturer.

For most, however, we tend to believe that a more general bag like the Therm-a-Rest Parsec is a better bet. Yes, it’s 7 ounces more than this bag, and yes, it’s not quite as warm, but for the average extra $225, you start to hit the level of diminishing returns, in our opinion. To be sure, this is one sweet bag — but be sure you really need all of it before pulling the trigger.

Consider the AlpinLite 20 if you are ready to invest in a high-quality product from a leading industry leader. Also be sure that you are someone who is very careful to take care of lightweight, sensitive gear. If that’s you, it’s one of the best backpacking sleeping bags money can buy.

The REI Co-op Radiant 20 ($199) is a value-packed sleeping bag that doesn’t compromise on warmth, and it allows for some space to toss and turn while still keeping the weight down.

Offered as an affordable alternative to the Magma series, the Radiant uses a polyester shell and 600-fill down to slide in below the $200 mark. However, it borrows many design features from high-end bags. REI gave this bag the same nine-size profile treatment as the Magma bags, meaning it’s easy to get into a bag tailored for you. Senior Editor Nick Belcaster used the medium size this summer and found the sizing to be spot on.

In addition to the 600-fill down, the footbox tucks in some synthetic insulation to prevent dampness where your feet might meet the tent walls. Smart. The bag shape lets in some extra space in the shoulders and hips, and our resident toss-and-turners had no complaints about being able to move around.

REI didn’t skimp on the Radiant’s little features to hit the price point, either: a decent draft collar encircles the face opening to trap warmth, an interior pocket secures your headlamp, and snag-free zipper sliders won’t damage your sleeping bag fabric in the middle of the night.

The Mountain Hardwear Bishop Pass 15 isn’t a vis-à-vis comparison to this bag, but the Radiant does pack in about 5 ounces more down in the same size, and that’s with a slightly warmer bag rating. The tradeoff is in weight, and the added synthetic fill in the REI bag does give it a ~5-ounce penalty. For the wallet savings, however, it’s a savvy trade.

For hundreds less than many other bags on the market, the Kelty Cosmic Down ($170-200) does a lot for a little. By using a budget-friendly 550-fill down and leaving out a few features, you get a perfectly serviceable sleeping sack for backpacking through the summer months.

There are two big differences between budget and higher-end sleeping bags: the insulation and the trimmings. In the Cosmic 20, a lower fill power 550 down means that it’s not quite as thermally efficient as, say, the 950-fill in a Feathered Friends bag, but it’s still lightyears nicer to pack compared to synthetic. You’ll mostly notice the difference in packed size with a lower fill power, and while a 10-liter compressed size isn’t bad, higher-performance bags can get down to 7 or 8.

The cut of the Cosmic Down is a classic mummy with a bit of space let in, which helps to shore up the lesser fill-power down, but still isn’t a constrictor. This is where we notice some of the cost-saving measures, however, and notably, the zippers on the Cosmic are lesser than other bags we’ve tested and don’t incorporate any anti-snag sliders. Still, with a careful touch, they work a treat, but need to be treated nicer than most.

While the Cosmic is undoubtedly bottom dollar, you can get a decently better bag if you’re willing to spend a little more. The Mountain Hardwear Bishop Pass 15 makes use of a nicer 650-fill down, ripstop nylon shell (compared to the taffeta used in this bag), is a bit warmer and is lighter. You’ll need to pay about double for the privilege, but after three seasons on both bags, the Bishop Pass is holding up a good bit better, so it’ll last longer.

Still, there’s plenty of other backpacking kit to buy, and if you just need a bag to get you through (or want to pad out your closet with a loaner bag), the Cosmic Down 20 is well up to the task. For the price, we think it’s one of the better budget options out there today.

Like the Katabatic Alsek, the Feathered Friends Flicker UL Quilt ($529) is made for those who want the ultimate in temperature control. In our opinion, it’s even a bit more versatile, with a full-length zipper that splits the quilt in two.

We used the Flicker for 5 years before rendering our verdict, and it reliably performed for us on everything from the Grand Canyon to an entire Appalachian Trail thru-hike. Size and packability are the two main features that drew us to this quilt, and it is impressive that it is both roomy enough to toss and turn in and packs down to the size of a football.

Available in 20-, 30-, and 40-degree versions (we tested the 20), the Flicker is st￭ with ultra-premium 950+ goose down. Feathered Friends doesn’t use water-resistant treatments on its down, which can inhibit the lofting ability of the feathers to some degree. This allows the down quality to shine through, and the Flicker supports our impression that Feathered Friends bags are rated for comfort, not limit.

Unzipping the full-length zip allows the quilt to splay open into a blanket that two full-grown campers can snuggle up underneath, a boon for warm evenings when you don’t need all that down. If things aren’t hot but you still need some added venting, we found the cinchable footbox to bleed off excess heat quite well.

The only long-term issue we’ve encountered is that, given enough time (and infrequent washings), the zipper can become grungy and unzip itself as we toss and turn. Washing the bag remedies this, but it highlights the differences between the Flicker and a zipper-less sleeping quilt.

At $529 for the 20-degree version, the Flicker UL is a bit pricier than the similarly specced Alsek (the 900-fill power version will run you $454) and about 4 ounces heavier. We think the Flicker UL is a perfect option for those not interested in making the full leap to a backless quilt, but still want to fine-tune their sleeping setup every night.

When it comes to ultralight and cutting edge gear, some of the bags on our list can be pretty pricey. But for those looking for packability and customization at a great value, the Sea to Summit Spark ($349-649) line is a worthwhile option. 

The technical side is exceptional: RDS-certified 850+ fill down, a PFAS-free DWR treatment, and a well-chosen 10D face fabric that feels like a dream — all combining so you’re snoozing both morally sound and in comfort.

The Spark also does a great job of showing off some well-thought-out specialized features, including a hybrid baffling system to limit down migration where it counts, a technically constructed hood that isn’t too big or too small, and a foot box design that ensures you’re not plantar flexing your feet all night. 

While it isn’t the absolute lightest bag on our list, or our top overall choice, it boasts a high degree of customization, from 0-degree to 45-degree options, half zips or full side zips, and the choice of regular, long, or women’s sizing. For those searching for a couple’s compatible bag, the full-length zip options can even zip together to form one large sleeping bag!

The Spark is a touch snug around the legs for the sizing, which won’t work for some larger folks, and it lacks a differential cut design, which we find to be an important feature for eliminating cold spots. For those looking for a bit more wiggle room, the Therm-a-Rest Quasar is a worthwhile option, and for those who don’t mind spending more, the Western Mountaineering AlpinLite gives the Spark a run for its money.

At the end of the day, the Sea to Summit Spark is a well-rounded ultralight bag that won’t let you down.

Cozy (and we mean it) face and internal fabric encapsulate the fluffy 800-fill pillow-like down of this bag, making it one of the more comfortable models we have tried and, ultimately, the best overall. The Therm-a-Rest Parsec ($470) is designed for lightweight chilly backcountry excursions — and we’d say it knocks it out of the park for a whole slew of different adventures.

A few key features nudge this unique bag above a lot of the winter-ready competition in our opinion. Therm-a-Rest added a baffled pocket of insulation to the toebox, d믭 a ‘Toe-asis Foot Warmer’, which rapidly traps heat around cold feet once you settle in for the night. This is a cherished addition, given some of our propensities for chilly extremities while sleeping.

We also appreciate the removable straps on the bottom of the bag (similar to those used in backpacking quilts). These straps can be secured around your sleeping pad, preventing you from sliding around and boosting the thermal efficiency of your sleep system. We take these off for missions where weight is a concern, but appreciate them when we can afford the luxury.

At over two pounds, the 0-degree version would be overkill for summer and some shoulder-season trips, but the warmth-to-weight ratio is quite stellar for a four-season sleeping bag. The 20-degree option we tested offers greater versatility for warmer excursions. Insulation is “heat-mapped” around the bag, concentrating on areas of your body where you need it most. This reduces the overall pack size and weight while still delivering a solid punch of heat when temps plummet.

For icy winter nights on long forays in the wilderness — or just about any adventure you could cook up — the Parsec 20-degree bag is the portable bed you need.

Ultralight backpacking quilts are gaining in popularity, and the Enlightened Equipment Enigma ($355) is certainly to thank for part of that rise. The Enigma is designed for the dedicated, weight-conscious backpacker wanting the most dialed, no-frills ultralight setup.

Having taken both the brand’s more blanket-like Revelation and Enigma on extended thru-hikes, we feel like the Enigma does a better job of reducing drafts, packs into your bag more easily, and is just a better quilt for backpacking in general.

Enlightened Equipment is known for the high level of customization it offers for its quilts, allowing the weight, warmth, size, durability, and style to be perfectly dialed for whatever adventure lies ahead. Check out the fully custom Enigma to find your perfect style. Just beware, these have some long lead times.

You can also choose between 7D, 10D, or 20D fabrics for the outside, and 7D and 10D for the inside to adjust the durability of the quilt. We found that a 10D outside and 7D inside held up just fine over months of abuse. The baffles are thoughtfully designed into a continuous U shape which reduces feather shifting, and the stitching between the baffles doesn’t go all the way through the quilt, eliminating cold spots.

The quilt also comes with an elastic strap attachment system for securing it to sleeping pads and a cinch cord at the neck to further eliminate drafts. We wish they had placed the pull cord on the side of the quilt, however, rather than right in the middle above your face, as it often gets annoying while trying to sleep — really, one of our only complaints.

In short, the Enigma Quilt is a reliable, ultralight, and super warm alternative to traditional sleeping bags while backpacking. For long thru-hikes spanning months or fast and light forays in the mountains, this thing will keep you toasty without weighing you down.

The Sea to Summit Hamelin ($176) combines all the camp-savvy functionalities of the brand’s higher-end bags into a budget-friendly synthetic option. This bag quickly became one of our bash-around favorites for chucking in the back of the truck and warm-weather camping trips, where down-filled bags can overheat in certain conditions.

We tested the 30-degree version this summer in the Pacific Northwest, where the ventilation options on the bag made it workable for outdoor overnight temperatures ranging from the low 40s to the high 70s. It’s tough to get a budget bag that covers a wide range, but the Hamelin does it well.

Like the brand’s more premium down-filled Ascent bags, the Hamelin hosts the ‘Free Flow’ full-length side zipper, which encircles the bag and opens up a multitude of different venting options. Our tester found that they most often started the night with the footbox unzipped and then would pin things up once the coldest part of the night had passed. You can even wear the bag around camp by using the snaps on the collar.

The packed size of this bag is pretty bulky, and certainly the largest relative to the temperature rating in our recommendations. That said, it’s certainly not as large as a rectangular synthetic bag, and in the 30-degree version — the one we recommend more — it’s manageable to even get into an ultralight backpack for a quick overnight.

Why do we recommend the REI Trailmade over this bag? A few reasons: First, the Trailmade is offered in six different sizes, compared to the four sizes of the Hamelin (men’s and women’s, plus regular and long). This provides more backpackers with an affordable option for entering the sport. Second, while the Trailmade has become slightly pricier since its debut (now priced at $119), it remains approximately $50 cheaper than the Hamelin.

That said, if you’re after the versatility and venting options that Sea to Summit has baked into this bag, the added spend might be trivial — it’s certainly a roomier and more comfortable bag than the Trailmade. Consider your needs before going either way.
