Norrona Falketind Flex1 Heavy Duty sturdy hiking pants are made for mountaineering and are suitable for all-season outdoor activities. Norrona is using two main fabrics in these pants. One is a high-quality plain weave nylon because of its durability, windproofness and breathability. And on the thighs, knees and seat Norrona uses a flex1 softshell fabric. Norrona uses this material because it offers excellent movement, durability, windproofness, high breathability, and effective moisture transportation. The primary fabric is a 200 g/m2 100% recycled plain weave nylon fabric, a mid-weight quality perfect for all-year use. The flex1 is a 250 g/m2 160D recycled double weave fabric to protect exposed areas, provide great stretch, and make the pants perfect for changing weather conditions. Both qualities are treated with PFC-free DWR for extra weather protection and durability. Key features include a custom-fit waist system, two hand pockets, a hidden gaiter hook, a thigh pocket, and Velcro
