"What Our Gearhead® Experts Are Saying: ""This hoody has been my go-to for everything from backcountry touring to brisk morning hikes. It’s super breathable but still blocks wind and sheds light weather. The waffle fleece interior feels great over a base layer, and it layers under a shell without bulk.""When we're out chasing cold starts or exposed ridgelines, the Black Diamond Coefficient Storm Hoody keeps us warm and moving. Designed as a do-it-all alpine midlayer, it blends breathable insulation with wind and water resistance for unpredictable mountain conditions. The gridded fleece interior traps heat while still letting moisture escape, and the stretchy outer fabric moves with us whether we’re skinning, scrambling, or hauling gear. It even packs into its own pocket with a loop for clipping to our harness or pack. Lightweight, versatile, and weather-ready, this layer works just as well on alpine starts as it does for coffee in town after."
