The Troy Lee Designs Ace Shorts feature a lightweight, tailored fit built for the roughest XC riding. The Ace is made with a breathable four way stretch polyester that is designed to accommodate your full range of motion in the saddle. Troy Lee also includes a large stretch panel on the back for added flexibility. The Ace possesses excellent moisture wicking capabilities to keep you dry, and welded intake and exit vents at the crotch keep the air flowing. But that's not all. Troy Lee includes additional thigh and crotch ventilation zippers to make sure you stay comfortable. The Ace's low profile pockets are located on the side of legs so you won't feel the contents while you pedal, and the adjustments tabs at the waist allow you secure the perfect fit. Finally, the mesh liner short includes a premium removable chamois that provides superb support on long rides.
