Why We Like The Stoney HS Pant

From scoping lines deep in the backcountry to searching for hidden gems at the resort, the Stoney gives us the freedom to find and shred the season's best turns. Mammut's DRYtech Pro material holds its own through rugged conditions and turns away icy gusts and deep powder, all while letting our skin breathe underneath to keep us comfortably dry.


  • Classic hardshell pant for back bowls and backcountry powder
  • 2-layer construction provides wind- and waterproof protection
  • Active stretch material follows your every move
  • Outer-thigh zippers allow you to dump excess heat
  • Hook-and-loop waist tabs provide a customized fit
  • Adjustable hem and elastic gaiter stop snow from packing in
  • Rugged kick patches provide increased durability
  • Back belt loop snaps connect to compatible jackets
  • Item #MAMU5D9
