The Fly Racing Evolution Evo off-road pants offer DST (Durable Stretch Technology) and are constructed from four-way 600D HEX Stretch fabric, providing excellent mobility. Laser-cut perforations and strategically placed stretch mesh give advanced airflow. Relaxed leg cuffs give variability, and the leather heat shield panels have Aramid stitching. Light mesh at the seat panel with an Advanced Lycra liner and a durable 900D seat increases comfort and performance. Fly Racing's Boa System offers adjustability along with the ratcheting fly closure. The Evolution Evo pants offer ergonomically pre-shaped knees that accommodate most knee braces and guards. Fly Racing's exclusive zip lock system keeps the pants securely closed.
