Clearance Piranha Gear Vale Tudo Shorts - Bones Grappling Shorts - White polyester With a slightly longer thigh length, fully lined (so it's a bit more... ahem... modest...), and an elasticized drawstring waist, we originally intended these for people that practice MMA, BJJ or UFC mixed martial arts... ...but they work just as well for Muay Thai, Kickboxing, Karate, Boxing, and anytime you want something a little more substantial than a Speedo type brief like under your wetsuit for SCUBA diving. A spandex / polyester blend (80/20) much higher than is typical with vale tudo shorts - we want these to last a long time - not get stretched out after six months. Sublimation printing so theres no "ink" to rub off or crack!
