When we built the Flex™ shorts, we started by taking things away. Things that fighters have told us they don’t want in their fight shorts. For starters, you won’t find any hardware on the shorts. Things like eyes, exposed laces, metal loops and rivets are out. You don’t need them weighing you down. We also took away all the Velcro. Some guys like Velcro, but let’s face it; for some, it’s a source of chafing and can lead to skin abrasions when you’re rolling on the mat.
