When the alpine calls but the weather forecast looks sketchy, the Black Diamond Coefficient Storm Hoody delivers the perfect balance of warmth, protection, and packability for women who refuse to let cold conditions dictate their adventures. This versatile stretch fleece jacket features a unique gridded interior construction that traps warmth while maintaining breathability during high-output activities, while the PFAS-free DWR coating sheds light precipitation and cuts through alpine winds. The intelligent design includes 8% elastane for unrestricted movement during technical climbs or scrambles, and when the sun finally breaks through or you start overheating, the entire jacket packs neatly into its own hand pocket with a carabiner loop for easy clipping to your harness or pack. Whether you're layering up for a dawn alpine start or need a reliable midlayer for unpredictable mountain weather, this storm hoody adapts to whatever the day throws at you.
