Touring, skinning, whatever you choose to call it, the Mammut Haldigrat Air HS Pant is built for it. With the help of the Pertex Shield Air 3L laminate that seals out the weather and breathes better than some pants we have worn in the past, we can skip up skin tracks on bluebird days and storm days with equal aplomb. Meanwhile, the burly nylon face fabric encourages adventurous routes, and the long outer-thigh zips help us stay cool, calm, and collected on exposed faces and precarious ridges.
