What Our Gearhead® Experts Are Saying:"This jacket is bomber. I’ve worn it for everything from glacier travel to storm skiing and it hasn’t flinched. The GORE-TEX Pro shell is insanely durable and breathable, and the ventilation zips and harness-compatible pockets make it perfect for mountaineering."When the weather gets nasty and the terrain gets serious, the Crater Pro HS Hooded Jacket is what we trust to keep us protected. Mammut crafted this technical alpine shell with a 3-layer GORE-TEX Pro membrane for maximum waterproofing and breathability, letting us move fast through rugged terrain, even in driving snow and wind. We appreciate the thoughtful alpine-ready features—backpack- and harness-compatible front pockets with water-repellent zippers, X-vented underarm zips for cooling without exposing us to the elements, and an articulated fit with pre-shaped sleeves for freedom of movement on exposed faces. Add in an adjustable hem with accessible drawcord, a helmet-compatible hood, and full-repair accessibility, and this jacket is ready to tackle big objectives and storm days alike.
