For your next trip to high heights, cold climates, and technical terrain, gear up with the Mammut Eigerjoch Pro In Hooded Jacket. Designed for mountaineering, this jacket has everything you need to thrive in extreme environments. The shell of the jacket is made up of Pertex Quantum Pro fabric, an ultralight material that repels water, resists abrasion, and adds almost no weight to your kit. On the inside you've got a combination of down and synthetic insulation for a one-two punch of warmth and comfort in cold conditions. PrimaLoft Gold insulation is placed in areas that are more sensitive to moisture buildup, giving you warm-when-wet warmth where it counts and reliable down insulation everywhere else.
