Pushing for the summit calls for pants that are protective from the elements but still allow our body to breathe and shed excess heat. The Mammut Aenergy Air HS Pants answer the call and feature a super breathable and waterproof Pertex Shield Air material for outstanding breathability and weather protection. Integrated gaiters help to keep the snow from getting into our boots and the 3/4-length side zips allow us to dump excess heat when we get too hot. The waistband has external Velcro waist adjustment tabs and leg width adjustments at the calf and ankle allowing us to get the perfect fit around our legs.
