The MMA shorts tend to be stretchy in certain areas, which makes them perfect for grappling. They aren’t going to rip and tear, and when you have a quality pair of shorts, they won’t roll up on you. The shorts will typically have a slit on each of the thighs, as well. These small slits will make it possible for you to kick properly without feeling constricted. Essentially, you don’t have to worry about the shorts getting in your way. They will help to facilitate your movement when training and fighting.
