Bauer's revolutionary 37.5 technology aims to turn sweat into energy by keeping body temperature at a minimum. 37.5 evaporates moisture up to 5 times faster than traditional fabric. Bauer has also included an odor resistance system featuring Sanitized to keep the jock shorts fresher for longer. Bauer's Premium Jock Short features an included cup, held securely in place with an internal sling and an elastic suspension system that should keep the player well protected. Also, strategic mesh inserts offer added ventilation keeping the player cool during gameplay. The compression jock short offers a locker loop at the back waist with flat lock seams to increase comfort and reduce chaffing. The shorts fit tight with compression for added mobility and increased blood flow.
