Campers who feel claustrophobic in tight mummy bags will love the Cochise’s stretchy construction. The baffles of this 15-degree, synthetic-fill bag are sewn with elastic fabric, so you can squirm around without resistance—and even sit cross-legged to cook or read. The other upside to this elasticity: When you stop thrashing about, it snugs the insulation around your body, eliminating heat-sucking voids. Testers also praised the Cochise’s rugged 50-denier fabric and its slew of amenities, including a stash pocket and sleeping-pad leashes (to keep your bag from sliding off your mat). The only downside: All those features and burly fabric add up, making the Cochise a bit heavy and bulky for its rating. 15°, 3.4 lbs;
