White and Black MMA Grappling Piranha Gear Blank Board Shorts (Flex-Panel) polyester ALL BLANK shorts - no embroidered logos or names on the outside. With a longer thigh length and split side seams for freedom of movement, we originally intended these for people that practice MMA or UFC mixed martial arts... ...but they work just as well for Karate, Boxing, Muay Thai, Kickboxing, and general grappling. We see lots of use for Crossfit training too, but do keep in mind these are made for optimal flexibility and freedom of movement - so they are looser than a swim suit might be!
