Norrona Fjora Flex1 classic Shorts are made for single-track mountain biking but work great for general outdoor activities such as trekking or mountaineering. The main fabric is a high-quality flex1 softshell fabric, and Norrona uses this because it offers excellent movement, durability, windproofness, high breathability, and effective moisture transportation. The primary fabric is a 145g/m2 plain weave 90x150D stretch mix consisting of 62% recycled nylon, 32% nylon, 6% elastane. The quality provides excellent stretch and is in the sweet spot of long-lasting durability and lightweight - perfect for long days on the bike. It is treated with PFC-free DWR to provide extra water repellency. The knees, thighs and seat are made in a more durable 205g/m2 90x150D fabric mix (69% recycled nylon, 19% nylon, 6% elastane). Key features include Custom-Fit Waist system, two hand pockets, a thigh pocket, mesh-lined front venting with a two-way zipper, and a silicon grip in the waistband. The shorts have a regular fit with an under the knee cut, and articulated legs and a higher waist for extra protection. The shorts are compatible with knee protection.
