Therm-A-Rest Antares 20

Despite the fact that it's the company's first sleeping bag in a decade, the Therm-A-Rest Antares 20F impressed us most after we comfortably weathered a few cold West Texas nights in it. The one-pound-15-ounce 750-fill bag pairs with the company's heat-reflective mattresses to trap warmth without adding bulk (or weight). [$350; thermarest.com]
