Sleep better and more comfortably with these synthetic and down sacks.

We took this year’s most promising sleeping bags out into the field to find the lightest, warmest, and most flexible models available. After months of testing, these were the ones we picked.

Rab Mythic Ultra 360

None

For committing expeditions, the Mythic offers premium performance at a premium price. There’s 900-fill goose down, and a clever construction that saves weight by using chevron-shaped baffles to hold down toward the center without using extra interior fabric. $650 Buy Now on Moosejaw / Read the Full Review

MontBell Seamless Down Hugger WR 900 #3

None

We’ve loved the Down Hugger since 2009 for its unparalleled stretch and warmth. Now you can add to the list: lightweight. Montbell slimmed the Down Hugger by eliminating baffles in favor of long strings of barbed yarn that hold the down in place. $589 Buy Now From Montbell / Read the Full Review

Marmot Yolla Bolly 30

None

Some campers go for the thinnest, tightest bag they can and accept the comfort tradeoff. But that’s not you. You want armfuls of insulation, plenty of space to move around, and reliable warmth. The semi-rectangular Yolla Bolly is the sack for you. $275 Buy Now on evo / Read the Full Review

NEMO Forte 35

None

With its combination of relaxed shape, low price point, recycled synthetic fill, and overachieving performance, this bag is a steal for campers who aren’t sure if traditional, down mummy bags are right for them. $160 Buy Now on Moosejaw / Read the Full Review

Therm-a-Rest Vesper 45

None

There are grapefruits larger than the packed size of this ultralight quilt. “I got everything I needed for a four-day mountaineering mission on California’s 13,150-foot Mt. Ritter into a 35-liter pack, thanks in large part to this quilt’s tiny packed size,” one tester says. $280 Buy Now on Moosejaw / Read the Full Review 

Big Agnes Torchlight UL 20

None

Warm summer nights turn three-season mummies into boil-in-bag situations, while cool fall nights make for shiverfests in summer-weight bags. Who knew that all we needed to bridge the gap between the two was an extra pair of long zippers? $400 Buy Now on Backcountry / Read the Full Review

Exped Waterbloc Pro

None

Weight-conscious hikers expect three-season bags to register under two pounds. This one does that and, thanks to a waterproof/breathable Pertex Quantum Pro shell, solves your condensation or rain worries, too. $679 Buy on Backpacking United / Read the Full Review

Looking to buy a sleeping bag? Consider the following:

  • Will it be wet where you’re planning to hike? Waterproof down and synthetic fill deals better with moisture than non-waterproofed feathers.
  • How cold will the weather be? Make sure you have a sleeping bag with a temp rating low enough to keep you comfortable, but don’t overdo it, or you might be lugging around extra weight in your pack for no reason.
  • Does your bag fit? Extra room in the foot of your bag can make it difficult to warm up. Buy too short, on the other hand, and your feet will compress the fill at the foot of the bag, negatively impacting its insulation properties.
