If you were lucky enough to tune into the Discovery Channel’s Man vs. Wild during its heyday, you might’ve witnessed Bear Grylls, a former British Special Air Service operator and the show’s host, make TV magic by gutting a dead camel and demonstrating how to climb inside the carcass for warmth and shelter. The sequence of teeth-clenching footage is perhaps the best reminder that hey, sleeping bags are pretty cool.Sleeping bags are a camping essential, and even those of us who never bed down under the stars typically keep one around the house as emergency bedding. We tend not to upgrade our sleeping bags with the same frequency as other pieces of outdoor gear, like hiking boots or down jackets. But sleeping bags have come a long way in the past decade. This guide, which we’ve organized by fill type and temperature rating, represents the best of the current class. Here's how to choose the best sleeping bag:

Temperature Ratings

Every sleeping bag comes with a temperature rating, usually represented, roughly, by a number in its name. That number comes from third-party lab testing. Those labs test for two numbers, a comfort rating, and a lower limit rating. The former is the environmental temperature in which a sleeping bag can provide sufficient warmth for colder sleepers; the lower limit rating represents the temperature at which a warm sleeper will be comfortable.The number in a sleeping bag’s name may not be its exact temperature rating; brands tend to round numbers to the nearest five or zero. For example, REI’s Trailbreak 30 has a lower limit rating of 29 degrees Fahrenheit and a comfort rating of 38 degrees Fahrenheit.Also, sleeping bags with lower temperature ratings typically use more material, so they will be bigger and take up more space in a backpack or closet.

Should You Get Down or Synthetic Insulation?

Sleeping bags provide warmth by trapping air inside their fluffy filling, which is typically either down or synthetic. Choosing which is right for you is a matter of pros and cons.Down, which comes from geese and ducks, tends to provide more warmth in a smaller volume than most synthetic insulation. Down insulation comes with a fill rating that denotes its quality. For instance, a 30-degree sleeping bag with 800-fill down will provide the same amount of warmth as a 650-fill bag rated to the same temperature, but it will do so with less insulation, so it will pack down smaller. Down’s main drawback is that it clumps when it gets wet, but many brands today use down that’s treated to be water-repellant. Down sleeping bags are also almost always more expensive than synthetic ones.

Synthetic insulation consists of manufactured fibers that attempt to mimic down. Synthetic insulation tends to be more water-resistant, durable and affordable but also bulkier and heavier.

Price

Depending how often you use it, a sleeping bag can last you for years; it’s a long-term investment. Sleeping bags are also expensive, and their price is a product of the materials used. As a rule, down insulation is more expensive than synthetic, and higher fill powers (more warmth for weight) are more expensive than lower ones. Because they use more material, cold-weather sleeping bags tend to be more expensive than warm-weather sleeping bags.

BEST OVERALL
The North Face The One Bag
The North Face

  • Variable temperature range means versatility

  • Not ideal for side sleepers

In terms of bang for buck, campers will be hard-pressed to find a better deal than The North Face's One Bag. The sleeping bag uses a modular zipper design that gives it a range from five degrees up to 40, eliminating the need to own multiple sleeping bags for camping in different environments. The One Bag is lightweight enough and packs down small enough for backpacking, too, especially if you leave the cold temperature layer at home.

Weight: 3 pounds 12 ounces (5°F); 2 pounds 12 ounces (20°F); 2 pounds 3 ounces (40°F)

Fill: 800-fill goose down

Compressed Volume: 17.5 liters (5°F); 13.5 liters (20°F); 9.1 liters (40°F)

BEST UPGRADE PICK
Nemo Riff 30 Sleeping Bag - Men's
Nemo Equipment

  • Extra room at the elbows and knees

  • Pricey for infrequent campers

Unique to Nemo sleeping bags is the "spoon" shape, which the company created for campers who want a mummy-style sleeping bag without the claustrophobia of actual mummification. The spoon shape isn't very spoon-like, but it offers extra room at the elbows and knees for shifting around and side sleeping. The Riff also includes zippered "gills" that extend its temperature range — just open them up and let the breeze in — making this sleeping bag supremely versatile.

For colder environments, the Riff also comes in a version rated to 15 degrees.

Weight: 1 pound 13 ounces

Fill: 800-fill PFC-free down

Compressed Volume: 5.5 liters

BEST BUDGET PICK
Kelty Cosmic 40 Sleeping Bag: 40F Down
Backcountry

  • Plenty of features for the price

  • Doesn't pack down very small

It's difficult to get a good sleeping bag for less than $100 — chances are you're just as well off bringing blankets from home. But for close to that price, you can get this full-featured mummy-style bag from Kelty. It's stuffed with 550-fill down insulation and includes a small zippered pocket for keeping essential items close and an extra baffle that prevents air from creeping in through the zipper (an underrated innovation). Compared to sleeping bags with similar temperature ratings, the primary downside is that this one won't pack down as small, so if you're backpacking or camping frequently, it might be worth investing up.

For colder camping, the Cosmic also comes in a 20-degree version.

Weight: 9.14 ounces

Fill: 550-fill down

Compressed Volume: 10 x 7 inches

BEST ULTRALIGHT OPTION
Big Agnes Torchlight UL 30 Sleeping Bag
Evo

  • Great for backpacking

  • Not ideal for warmer weather

Lighter, more packable sleeping bags exist, but not with the same unique suite of features as Big Agnes's Torchlight UL, which weighs one pound 12 ounces in a regular length. Primary among those are extra zippers on either side that expand the bag's size when opened. It's a nice touch, given that ultralight sleeping bags can sometimes be confining. The Torchlight also has an adjustable hood, water-repellent 850-fill down insulation and even an interior pocket for small essentials.

The Torchlight UL also comes in a 20-degree version.

Weight: 1 pound 12 ounces

Fill: 850-fill DownTek

Compressed Volume: 5 x 6 inches

BEST CASUAL SLEEPING BAG
REI Siesta Hooded 25 Sleeping Bag
REI

  • Great for casual campers

  • Not as technical as competitors

If you aren't camping in a way that puts packing space at a premium, then it might not make sense to confine yourself to a mummy-style sleeping bag. That doesn't mean you should go for a low-grade bedroll, though. REI's Siesta is the perfect compromise — it has enough synthetic insulation for temps down to 25 degrees, and both its sides have zippers (one full-length, one partial) so that you can flip down its top like the duvet on your bed at home.

Weight: 4 pounds 6 ounces

Fill: synthetic (polyester)

Compressed Volume: n/a

MOST INNOVATIVE DESIGN
ust Monarch Sleeping Bag
REI
ust

  • Innovative design
  • Soft materials

  • Bulky

Sleeping bags traditionally follow a pretty standard formula when it comes to shape, but UST's Monarch is for those that like to think outside the box. The bag is essentially a three-in-one option, thanks to two wings on either side of the bag that can be folded over, or under the sleeper, providing varying levels of insulation. For colder environments, flip both wings over the body for your warmest sleep. For warmer temps, do the inverse and fling them to the side. Just don't hit your fellow campers in the process).

Weight: 4 pounds, 7 ounces

Fill: Body: 150 g recycled synthetic poly; wings: 220 g recycled synthetic poly

Compressed Volume: 13.5 liters

BEST FOR WET ENVIRONMENTS
Montbell Seamless Down Hugger WR 900 #3
Montbell

  • Weather-resistant

  • An investment piece (aka, pricey)

Montbell's crop of Down Hugger bags has a lot going for them. For one, Montbell secured this bag's down insulation in place using a system that it calls Spider Baffle, where an array of synthetic threads hold onto down clumps to help maintain their loft. It eliminates the need for baffles created by stitching, optimizing the bag for warmth and durability. Montbell employed elastic in the liner to help the bag "hug" a sleeper, eliminating dead airspace (in our testing, we didn't find this feature claustrophobic). To top it all off, this particular Down Hugger model comes with a Gore-Tex Infinium exterior, making it remarkably weather-resistant.

The Down Hugger WR 900 #3 is rated to 30 degrees Fahrenheit. It also comes in 15-degree, 25-degree and 40-degree models.

Weight: 1 pound 3.6 ounces

Fill: 900-fill Power EX Down

Compressed Volume: 5.5 x 10.9 inches, 3.8 liters

BEST FOR SIDE SLEEPERS
Big Agnes Sidewinder SL 35˚
Big Agnes

  • Design caters to side sleepers

  • Not tapered like a traditional mummy

Big Agnes makes the Sidewinder specifically for side sleepers. It's apparent, too: the bag's hood opening faces to the side. Its form isn't as tapered as typical mummy-style bags, but that's intentional to allow side sleepers to bend their knees inside and shift foot position. While most of the Sidewinder's insulation is down, Big Agnes reinforced these regions with synthetic insulation in these areas to allow for that shifting, too. Lastly, there's a pocket in the hood for a pillow that enables it to move from one side to another if you decide to switch sides.

This sleeping bag also comes in a model rated to 20 degrees.

Weight: 2 pounds

Fill: 650-fill DownTek

Compressed Volume: 7.5 x 15 inches

BEST FOR HUNTING
Sitka Kelvin Aerolite 30 Sleeping Bag
Sitka

  • Can transform into a layer for bivvying

  • Over-engineered for the non-hunter

Hunting doesn't necessarily call for a different sort of sleeping bag, but Sitka believes hunters should have one regardless. Knowing that stalking game requires patience and, at times, hunkering on the damp ground for a long time, it gave the Aerolite 30 arm slots and a bottom you can open and tuck out of the way, transforming this bag into a functional warm layer you can bivy down in while remaining mobile. It's filled with PrimaLoft's Gold Insulation with Cross Core tech, which comes from NASA and won't lose its warming power when damp.

Weight: 2 pounds 6 ounces

Fill: PrimaLoft Gold with Cross Core (synthetic)

Compressed Volume: n/a

BEST TWO-PERSON SLEEPING BAG
Big Agnes Camp Robber Bedroll
Big Agnes

  • Cozy and great for sleeping with a partner

  • Not as warm as bags with a hood

For most of us, camping is rarely, if ever, a solo activity. Part of the joy of spending time outside is doing so with your significant other. But designs that let you zip two sleeping bags together are cumbersome at best, so Big Agnes made one bag to fit two. The best thing about the Camp Robber is its versatility — zip the plush top quilt to the bottom layer for a sleeping bag fit for two, or fold and zip the doublewide quilt to make a single sleeping bag.

Weight: 3 pounds 6 ounces

Fill: 650-fill down, DownTex hydrophobic treatment

Compressed Volume: 10 x 10 inches

BEST TRAIL QUILT
Therm-a-Rest Vesper 45F/7C Quilt
Therm-a-Rest

  • Light and packable

  • Hood enthusiasts will miss the feature

The best option for a warm-weather sleeping bag isn't a sleeping bag at all; it's a quilt. Trail quilts have been a go-to for ultralight backpackers for a while but are increasingly becoming popular amongst more mainstream campers. With less material, trail quilts are lighter and more packable. Therm-a-Rest's Vesper 45 is an excellent intro to this offshoot category — at 12 ounces, the quilt will go unnoticed in a backpack, but it still has functional features like an enclosed foot box and straps to secure it to a sleeping pad.

Trail quilts work in cold environments too, and the Vesper is also available in a 32-degree version and a 20-degree version.

Weight: 12 ounces

Fill: 900-fill Nikwax hydrophobic down

Compressed Volume: 4.5 x 6 inches
