Whether youre working your way along the ridge of an 18,000-foot peak or climbing an overhang behind a frozen waterfall, the Kayland Mens M11 Boots keep your feet warm and dry. An eVent liner stops moisture from seeping in but lets your perspiration out. PrimaLoft insulation is warm, lightweight, and super compressible like down, yet it continues to work even when wet. The integrated gaiters block ice and spindrift and stop your pants from riding up during overhung dry tooling. Laces that go all the way to the toes ensure a precise fit, and Vibram Teton lugged outsoles give you traction on the icy, snowy approach.
