Norrna’s lightest and most breathable mountaineering hiking pants These lightweight, softshell pants are made for mountaineering and are suitable for all-season outdoor activities. The main fabric is a high-quality flex1 softshell fabric, and we use this material because it offers excellent movement, durability, windproofness, high breathability, and effective moisture transportation. The fabric is a 200g/m (denier 90) 69% recycled polyamide, 19% recycled polyester and 12% elastane double weaved flex1 fabric, a mid-weight quality perfect for year-round use. It is treated with PFC-free DWR to provide extra water repellency. The pants have a regular fit with articulated knees to improve mobility during vertical movement. They can be worn over hiking boots and light ski touring boots.
