Designed for alpine climbers and mountaineers who need versatile yet dependable warmth in the mountains, the Rab Men's Electron Pro Down Jacket offers mid-weight insulation for high-elevation adventures. The lofty down is housed in a super durable weatherproof outer fabric that's made to withstand wear, wind, and water, and Rab mapped the baffling for added warmth in critical areas like the torso without compromising weight or packability. Key details like stretchy, low-profile cuffs for seamless layering, a two-way front zipper for fuss-free belaying, and an adjustable, helmet-compatible hood make this advanced mountaineering layer stand apart from the rest.
