Score one for the rainforest. The Compression Jock Pants are made with 38% bamboo, which helps in the cleanliness of the pants. Not only is the bamboo antibacterial, but it is a natural moisture-wicking component that even helps keep odors away. This keeps your pants fresher longer, allowing you to play in maximum comfort late in games. The Compression Jock Pants feature a true body fit, meaning that they are made to contour to your body. The flatlock seam construction even helps reduce chafing, keeping your mind and body focused on the task at hand. Included is the Pro-Fit Cup, which is a hard cup that is covered by a soft shell. It is ultra lightweight and even features small cooling vents to keep you dryer for longer. The flex sides fit your body better to provide supreme comfort. Please note: Jocks and underwear are not returnable/exchangeable for any reasons except for shipper error.
