Black Diamond W Coefficient Hoody

A high-output midlayer for climbers, ski tourers, and trail athletes who need fast moisture movement and active warmth in a piece that fits cleanly under a shell, the Women's Coefficient Hoody from Black Diamond delivers. This go-to layer uses Polartec Power Dry fleece at 180 gsm with a gridded interior that traps a thin insulating air layer against the skin when stationary and actively wicks sweat away during sustained effort. The pattern dries faster than traditional fleece constructions, reducing the clammy transition effect between sustained uphill effort and cold transitions. An under-the-helmet-compatible hood, full-length zipper for ventilation control, and stretch cuffs with integrated thumbholes complete the functional details, and a slim cut moves cleanly under a hardshell without adding bulk to the layering system.
