Sizing Charts

Please note:  Because we sell from various manufacturers, we have done our best to compile the sizing charts below. Please review carefully before ordering.

For Diamond MMA Products:

Your Diamonds are made to fit tight but comfortable. If you are thicker in the thighs and/or seat, go up a size. If you have any questions about sizing, feel free to contact us with questions. We are happy to help you get fitted.
Diamond MMA is so confident in our product that we offer you a lifetime guarantee on your athletic cup. If you have any issues with it you can contact us and we will send you out a new one free of charge! Because shorts and jocks naturally wear, we offer a 30 day warranty on our compression shorts and jock straps.
