Durability
3 A Grand Canyon backcountry ranger says, “I snagged the shell several times on thorns around camp, but it didn’t tear.” However, the 40-denier, DWR-treated polyester sustained the most pilling in our abrasion test.

Warmth
3.5 The proprietary synthetic fill is a blend of different fiber lengths. According to the company, the long fibers boost durability, while short fibers are better at trapping warmth. “We had multiple nights of subfreezing temps combined with steady 20-mph winds in the Grand Canyon, but I slept like a baby, even though I was tentless,” a tester says.

Fit
3.5 Our tester praised the sculpted hood, which fit snugly and held his fleece jacket-pillow in place throughout the night. “I also liked the trapezoidal footbox, which naturally draped over my feet,” he says.

Features
3 Testers lauded the smooth-running zippers and anti-snag tape, but lamented the bulky (8 by 18 inches) packed size. The bottom has no insulation, but elastic straps keep a pad securely attached.
