The lightweight standard for the death zone. The Olympus Mons Pro is the definitive choice for high-altitude alpinism, engineered to keep you moving in the thin air of the world's 8000-meter peaks. Weighing in at an astounding 940g—lighter than many single leather mountaineering boots—it completely redefines the weight penalty of extreme warmth. This double boot system utilizes a "Core-Wrap" construction to maximize thermal efficiency without the bulk of traditional "moon boots," while the external BOA® Fit System allows you to micro-adjust the fit without ever unzipping the gaiter or exposing your hands to the biting cold.
