Fast-paced tours to alpine expeditions.

Loaded with a bevy of smart features and technical fabric details, the Arc'teryx Men's Beta AR Pant protects you from the elements when you're facing down gale-force winds, heavy snow squalls, and freezing temperatures. Featuring Gore-Tex Pro 3-layer membrane/laminate construction, these pants are seriously equipped for the worst weather on the planet. Furthermore, you'll appreciate the pant's athletic fit, with ergonomic-3D patterning for exceptional freedom of movement over base layers.

Arc'teryx placed a Gore-Tex 3-layer Pro membrane/laminate throughout the entire pant, but with slightly varying face fabrics in strategic locations or what it dubs as "Hybrid Mapping" technology. Basically, you'll find N40r-X Gore-Tex Pro 3-layer body for lightweight, ultra-breathable performance, without sacrificing premium waterproof protection. Reinforced along the seat, knees, and lower legs, N80p-X Gore-Tex Pro 3-layer construction beefs up durability, allowing for worry-free wear in the most grueling environments on earth. Add in fully taped seams and watertight zippers for a near-impenetrable fortress against all-day deluges, sopping spring snow, and deep powder.

And because these pants are designed for alpine climbing and ski-mountaineering approaches, you'll find an adjustable webbing belt that tightens comfortably under your favorite climbing harness, as well as 3/4-length ventilation zippers for easy integration over crampons. Other key features included Keprotec instep patches for enhanced protection against crampon and boot-related damage, as well as Cordura PowderCuffs with bootlace hooks to seal-out snow and outside moisture.
