The Feather is HighSierra Co.'s answer to the question "what's the lightest bag I can bring on a summer trip without freezing?" At 1 lb 12 oz, it weighs less than most people's water bottle setup — and with a 750 fill-power down fill and an ISO lower limit of 35°F, it's legitimately functional for July and August trips in the Sierras, Cascades, and Rockies.

The 10D shell fabric shaves every possible gram without sacrificing meaningful durability for a bag in its weight class. A full-length zipper with anti-snag tape and a contoured hood round out a design that's pure minimalism — nothing included that doesn't earn its weight.
