Gear Review: MontBell U.L. Down Inner Pants

Five-ounce down pants that provide instant warmth after bone-chilling hikes.

Crave the warmth of down pants without the diaper-like bulk? These 5-ounce minimalists provide instant warmth after bone-chilling hikes. “They were my salvation after a six-hour slog through wet snow,” declares an Alaska tester. Credit two ounces of 800-fill down, which provides maximum warmth for minimum bulk (they pack down to liter-bottle size). Sewn-through baffles keep the feathers from migrating. The DWR keeps the insulation dry and lofty—light precip beaded on the shell—and the 20-denier nylon is surprisingly wind resistant and durable.

To keep weight low, features are few: no pockets, a basic drawcord to cinch the elastic waist, and a fly on the men’s version.
