An alpine specialist.
From winter ascents in the North Cascades to technical ice routes in the Canadian Rockies, the Arc''teryx Women''s Alpha AR Pant handles all of your tool-swinging and French-stepping needs. Being a member of Arc''teryx''s Alpha line, this pant has an alpine-specific design geared towards ice climbing and general mountaineering. Utilizing a Gore-Tex Pro Shell, which is one of the best waterproof and breathable membranes available on the market, the Alpha AR provides reliable waterproof protection when you''re confronted with unpredictable alpine weather and warming ice. The shell''s fully taped seams feature a low-profile design to minimize weight and bulk, which is especially valuable when you''re packing for a month-long expedition.
Arc''teryx is known for making simple and efficient pieces of clothing, and the Alpha AR is no exception. A full-length side zip offers quick and generous ventilation when you need to dump excess heat, and the integrated waist belt and suspenders allow you to make quick adjustments to the fit. The athletic fit with e3D patterning makes wearing a harness more comfortable, while articulated knees and an inseam gusset promote mobility when climbing vertical ice or mixed routes. Arc''teryx even equipped the pant with an internal LegWrap to prevent crampon snags when you''re walking or climbing. Durability is a must for whatever piece of gear you take into the alpine, so Arc''teryx reinforced the Alpha AR in key areas to boost the overall durability of the pant and added super burly Keprotec instep patches to resist wear from crampons and ice shrapnel.
