Product details

  • Description

    The shell is polycarbonate (same material as bullet proof glass), a rigid plastic that holds its shape on impact. The cup’s geometry helps deflect and spread the force of a hit away from one spot.

    A soft rubber elastomer rim lines the edges, so the cup sits comfortably against your body and helps reduce rubbing.

    It’s sized to fit the tailor-fit cup pocket in every Diamond MMA jock and short. Paired with our four-strap design, the jock helps keep the cup snug against the body so it stays put through every play.

  • Materials & care

    Shell: Polycarbonate

    Rim: Soft rubber elastomer

    Sizes: Youth 5.5" x 3" x 2" · Adult 6.75" x 4" x 2.25"

    Care: Leave it in your jock’s cup pocket and machine wash cold, then air dry. Or wash it by hand.

  • Warranty

    Every Diamond MMA athletic cup has a lifetime warranty. If your cup is damaged during normal use, submit a claim through our returns portal.

What makes the Diamond MMA cup different?

Two things: what it’s made of and how it’s held. The polycarbonate shell holds its shape on impact, and its geometry helps deflect and spread the force of a hit. The soft rubber rim keeps the edges comfortable. Then every Diamond MMA jock holds the cup in a tailor-fit pocket with four straps, which helps keep it snug against the body instead of shifting around.

Protective gear helps reduce risk but can’t prevent every injury.

Frequently asked questions

What size athletic cup should I get?

Match the cup to your build. The adult cup is 6.75" long, 4" wide and 2.25" deep, for full coverage on most adult athletes. The youth cup is 5.5" long, 3" wide and 2" deep, for younger athletes, teens and smaller-framed adults. Check the cup size guide to compare.
Is it a hard cup or a soft cup?

Hard. The shell is polycarbonate, so it holds its shape on impact instead of compressing like soft padding. The cup’s geometry helps deflect and spread the force of a hit, and a soft rubber elastomer rim cushions the edges.
What jock does it fit?

The cup fits the tailor-fit cup pocket in every Diamond MMA jock and short:

Our briefs don’t have a cup pocket and aren’t made to be worn with a cup.
What sports is it for?

Baseball and softball, hockey, football, lacrosse, wrestling, MMA, boxing, Muay Thai, jiu jitsu and other sports where groin protection is needed.
How do I clean the cup?

Leave it in your Diamond MMA jock’s cup pocket and machine wash cold, then air dry both. You can also wash the cup by hand.
What does the warranty cover?

The athletic cup has a lifetime warranty. Every other Diamond MMA product, including the jock short, has a 30-day warranty. Fill out the Warranty Claim Form if you have a problem.
How much is shipping?

Shipping is calculated at checkout, with Ground, 2-Day and Overnight options. U.S. orders over $175 ship free.
What if it’s the wrong size?

Exchanges are free, so you can swap for the right size. You can also return it within 30 days of delivery, or 60 days if you register your warranty. Add Checkout+ at checkout for free returns and package protection.
