The Mammut Crater HS Hooded Jacket Men is a 3-layer GORE-TEX® jacket that is at home on stormy peaks. The Crater is robust. It can take anything that the high-altitude mountain world throws at it: gusts, rain and snow. Because the GORE-TEX® membrane is located between the two protective textiles, the weather protection lasts longer. Features such as the helmet-compatible hood, underarm zippers for optimum ventilation during strenuous ascents, and the climbing harness-compatible side pockets provide the perfect basis for high alpine adventures.
