Large rear stretch panel inserts provide increased comfort and flexibility to the waist and lower back with lightweight and ventilated mesh with stretch panel inserts for an improved fit and excellent freedom of movement. Heavy poly-fabric reinforcement on the seating area and inner leg panels provide superior abrasion resistance and leather-reinforced inner-leg panels for heat resistance, grip and durability. Pre-curved ergonomic legs give superior comfort in the riding position, and innovative 3D knee construction and hidden expansion panels accommodate knee protectors. A convenient interior hip pocket allows storage for keys/coins, and a ratchet closure with dual waist adjustment gives a secure and custom fit.
