Patagonia M10 Storm Jacket - Men's Clement Blue, XL

What Our Gearhead(R) Experts Are Saying: "I use the M10 Storm Jacket when I want a true waterproof shell without the weight penalty. It moves incredibly well on the skintrack, disappears in the pack, and still blocks wind and snow when things get exposed. For fast-and-light touring, it's one of the most dialed shells I've worn." We reach for the M10 Storm Jacket when speed, efficiency, and weather protection all matter at once. Built by Patagonia for high-alpine objectives and long touring days, this shell keeps us moving uphill without feeling bulky or restrictive. It's the jacket we trust when the plan involves big vert, changing conditions, and no time to waste. Patagonia's 3-layer H2No Performance Standard membrane delivers reliable waterproof protection while maintaining breathability during sustained climbs. The slim, streamlined fit reduces excess fabric, the helmet-compatible hood seals out blowing snow, and chest pockets stay accessible with a pack on. Lightweight, packable, and purpose-built, the M10 Storm Jacket is made for demanding mountain missions where every ounce counts.
