Black Diamond M Access Down 2.0 Vest

A packable down vest for climbers and mountain athletes who want core warmth without sleeve bulk, the Men's Access Down 2.0 Vest from Black Diamond uses 800-fill Allied HyperDRY goose down in a slim-fit profile that layers cleanly over base layers and under shells. Allied HyperDRY treatment bonds hydrophobic chemistry directly to the down clusters, maintaining loft in humid or damp conditions where standard down would compress and lose warmth output. A PFAS-free DWR on the shell face handles surface moisture, and the vest stuffs into its own hand pocket for compact stowage during high-output sections where the extra warmth isn't needed. The 800-fill HyperDRY construction positions this at the top of the Access Down vest line, delivering efficient warmth-to-weight performance suited to three-season mountain use and fast-and-light objectives.
