When conditions in the mountains are cold and crisp, we don't leave home without our Mammut Stoney HS Thermo Pant. The 2-layer Mammut DRY Tour membrane blocks wind and snow, keeping our lower body dry and comfortable while skiing through deep fields of powder, and the synthetic insulation provides lightweight warmth so we can make the most out of bomber days. Two side zips keep cool air flowing when we're working up a sweat, and the adjustable waistband locks in a secure fit, giving us the freedom to bounce off side hits and play in the terrain park.
