Black Diamond M Deploy Down 0.5 Pullover Hoody

The lightest down hoody Black Diamond builds, the Men's Deploy Down 0.5 Pullover Hoody is a fast-and-light insulation layer for ski mountaineers, alpinists, and ultralight backpackers who measure every gram in the pack. 1000-fill goose down delivers the highest warmth-to-weight ratio commercially available, and the half-zip pullover construction trims fabric and zipper weight against a full-zip cut. A helmet-compatible hood seals out wind during quick belay swaps and rest stops, and the jacket packs into its own internal stow pocket so it lives at the top of a pack without adding bulk. At 148 grams in size medium, the Deploy 0.5 is the lightest of Black Diamond's Deploy Down line, sitting below the heavier Deploy Down 1.0 in the same family. The 1000-fill power and 148-gram total weight make this the appropriate rest-stop and emergency belay layer for fast objectives where a heavier insulator would not get carried at all.
