This 10°F bag is ruthlessly pared down for low weight and high performance–and it works. The essential ingredients: the highest quality 850-plus down; a water-resistant Epic by Nextec shell; and an efficient, precision mummy cut that saves weight without squeezing too tight in the torso. "It's a great shoulder-season alpine bag, especially for beefy guys," said one stocky 5'11" tester.
It's five to 10 degrees warmer than most bags in this weight class, which our cold sleepers loved on frosty October nights in the High Sierra and Rockies. The shell repels all condensation short of a downpour, the hood closes snugly with a simple snap closure, and the zipper runs smoothly–an anomaly on ultralight bags with wispy fabrics. $420; 2 lbs. 5 oz; 10°F
