The Shock Doctor Compression Hockey Jock Pants have a close-to-the-body, compression style fit that enhances comfort and support. They have a silicone grip pattern on the lower legs to better prevent shin pad slippage and keep them locked on the legs. The Core Flex Pocket design positions the lower third of the BioFlex Cup pocket in a much more natural position so your legs can freely move but the protection stays where it should. The Motion Control Cup System positions the BioFlex Cup pocket in a much more natural position so your legs can freely move but the protection stays where it should. Four-way stretch fabric moves with the body and comes with strategic venting on the back and groin area for premium moisture control and breathability. Velcro sock tabs then ensure your hockey socks stay locked on the jock throughout the game. Jock Size Waist Cup Size Small 22" - 24" Small Medium 24" - 26" Small Large 26" - 28" Small
