Durability
3.5 The DWR-coated, 40-denier ripstop nylon shell is immune to sticks, stones, and moderate precipitation. “We issue this bag to students,” says one tester who leads lengthy wilderness therapy courses. “It sees 70-plus straight nights of use four times a year, and holds up to this abuse for about two years before losing any loft.”

Warmth
3.5 Instead of traditional baffles and seams, this bag has welded shingles of synthetic insulation, which eliminate cold spots. “I got stuck tentless in a surprise May snowstorm,” says a Utah tester. “But even under a layer of snow and frost, my legs and core stayed warm and dry.” Gripe: The shallow, smallish hood was insufficient on nights below the mid-20s.

Fit
2.5 The 31.5-inch shoulder width is slightly north of average, but the thermally efficient legs and footbox may be too narrow for some. “My feet stayed warm, but there isn’t much space to stretch my legs or fit extra gear,” one tester says.

Features
3 The full-length zipper allows venting on warmer nights, but it constantly snagged, making late-night escapes frustrating.
