Mammut's Fall Line HS Thermo Pant was built for taking the lift up before bootpacking across ridgelines to take the biggest line on the mountain back to the bottom. The pants offer the reliable warmth and protection we need with body-mapped synthetic insulation and a waterproof DRY Tour membrane that allows us to dive deep into fresh powder without reservations. The adjustable waist ensures the pants stay secure while we work down steep terrain, and the integrated gaiters keep snow from packing into our boots.
