When dramatic changes in weather, terrain, and physical demands can occur, alpinists need clothing created to meet the demands. Constructed from 80-denier Gore-Tex Pro, the Arc'teryx Women's Gamma MX Pants delivers exceptional durability, yet is supple and resilient. Engineered to shed water, snow and resist abrasion, the fabric's face utilises larger yarns that are very tightly woven to create a smooth but highly abrasion resistant surface. Incredibly durable 150-denier Gore-Tex Pro is used for reinforcement in high stress areas. High coverage in the chest and the back keeps out snow, drafts and retains essential body heat, and the harness-friendly three-quarter-length side zips show an attention to detail meant for people who go to extremes.Guides, climbers and anyone doing alpine work for extended periods in difficult conditions will immediately appreciate the women-specific design with its focus on fit and movement. The athletic fit is streamlined but accommodates layers, and the patterning allows freedom of movement, especially vital while climbing.The low profile water-resistant zips reduce irritation under a harness or pack, and the two large, easily accessible bellowed chest pockets lay flat when not in use. Arc'teryx' removable internal LegWrap is an effective means of pulling in fabric volume to reduce crampon snags. Keprotec patches shield the insteps from cuts and abrasion, and bootlace hooks help keep the hems secure.
