What Our Gearhead(R) Experts Are Saying: "I've ridden these on cool, windy trail days and they strike a great balance between protection and breathability. The flex1 fabric stretches naturally when I'm climbing or moving around the bike, and the reinforced knees and seat hold up to rough terrain. The zip vents are clutch when the pace picks up."When the trail turns rugged and the wind cuts across exposed ridgelines, we zip into the Fjora Flex1 Pants and keep pushing. Norrona designed these mountain bike-specific pants with flex1 softshell fabric that blocks wind while remaining breathable enough for long climbs and technical descents. The stretchy, durable construction moves fluidly with every pedal stroke, supported by articulated knees and targeted stretch panels for unrestricted mobility. Reinforced knees and a reinforced seat stand up to repeated trail abuse, while zippered ventilation with mesh backing allows us to dump heat when the effort intensifies. A Custom-fit waist system(TM), high back waistband, and silicone grip keep everything securely in place, and adjustable ankle closures fine-tune the fit over pads. Built with over 50% recycled synthetic fibers and finished with a PFC-free DWR, these pants combine performance durability with responsible construction for serious trail days.
