A durable mountain biking baselayer. This long sleeve shirt is made for freeride mountain biking and is perfect for all outdoor activities. We use a high quality treated knitted tech polyester because it offers great durability. In key areas we use a flex1 softshell material because it offers excellent movement, durability, windproofness, high breathability, and effective moisture transportation. The main material is 100% recycled polyester 113 g/m2. It has been treated with HeiQ Fresh FFL anti-odor treatment. HeiQ Fresh FFL is a bio-based amino sugar polymer that is silver-free and not an antimicrobial. It removes the fat and protein from sweat, thereby eliminating the ability of the bacteria to grow and therefore reduce odor. On the elbows and cuffs, we use a ripstop 85% recycled nylon/15% elastane Flex1 blend 162 g/m2.
