The Fly Racing F-16 Motocross Pants are off-road trousers made from highly durable 600D polyester with multi-directional stretch ribbing for added movement and a mesh comfort liner to keep you fresh. Ergonomically designed pre-shaped knees can accommodate knee braces, and guards and the ratcheting fly closure allows for variable sizing. Low profile stretch leg cuffs mean these suit all boots and legs and these also come with a YKK main zip for durability.
