WARMTH The 1.25-inch-deep wells between the V-shaped chambers make space for a bag to loft underneath you, instead of compressing under your body weight. Combined with a continuous filament synthetic for a 4.4 R-value*, this pad helped testers stay warm in sub-freezing temps. “Bivying on an elevated platform with temps in the 20s is usually a recipe for a shivery night, but this pad kept the cold air from creeping into my bones,” our tester said after a weekend in Oregon’s Wallowas.
COMFORT “The 2.5-inch-thick, V-shaped chambers are extremely supportive for my chronically sore back,” our tester reports. Extra credit: The pad compresses to 5 by 8 inches.
DURABILITY The 75-denier polyester fabric was tough enough to handle our notoriously abusive tester, who punctured two other pads this season. $90; 1 lb. 9 oz.; 23x72x2.5; klymit.com
*R-value represents a material’s resistance to heat flow. The higher the number—they go up to 8—the better the pad’s insulation.
