PLENTY OF ELBOW ROOM
With elastic in each baffle, this bag expands as you toss, turn, and even sit up cross-legged to cook or play cards. When you finally stop thrashing, the bag’s elastic keeps the thick sheets of MontBell’s house-brand synthetic insulation close to your body, so you won’t have to heat dead air. Not especially tall? A cinch cord at the bottom of the bag seals off the space you don’t need. All that elastic adds up, though—it’s a tad heavy, even for a zero-degree bag, though worth every ounce if traditional mummy bags make you feel claustrophobic. Bonus: It’s also available in six additional degree ratings. 0°, 5 lbs; montbell.us
