Description

The Diamond MMA Quad Strap Jock is the ultimate in groin protection for high-impact sports and umpires. It delivers highly effective groin protection without sacrificing comfort.

Designed by award winning designers and Stanford University engineers, the system has been approved by Doctors and Urologists.

Made from military grade elastics and premium construction, the Diamond MMA groin guard system leverages a high performance 4-strap jock system to hold a specially designed athletic cup in place within a perfectly tailored cup pocket. This patent pending system prevents both lateral and vertical movement of the cup. 

In combination with the Diamond MMA Quad Strap jock, the cup stays completely in place with dedicated straps to minimize both lateral and vertical movement. The Diamond MMA high performance cup is used by athletes, the US military, and, of course, umpires

    Great product! The quad strap system really keeps everything in place, even during the most rigorous workouts. The material is breathable and doesn’t chafe. Definitely worth the investment.

    Sarah Lee – February 26, 2025

    I’ve tried several jockstraps, but this one stands out. The diamond design is not just for looks—it adds extra support. However, it’s a bit pricey compared to other brands.

  5. Rated 4 out of 5

    David Martinez – April 11, 2025

    The Diamond MMA Quad Strap Jock is solid. It’s comfortable and provides excellent support. The only downside is that it takes a bit of time to adjust the straps properly.

  6. Rated 5 out of 5

    Jessica Brown – April 27, 2025

    This jockstrap is a must-have for MMA training. The quad straps offer superior support, and the material is high-quality. It’s a bit snug at first, but it breaks in nicely.

  7. Rated 4 out of 5

    I was skeptical about the Diamond MMA Quad Strap Jock at first, but it has exceeded my expectations. The quad straps really do make a difference in terms of support and mobility. It’s well-constructed and feels like it will last for years. The only downside is that it took a bit of adjusting to get the straps just right, but once I did, it was perfect. A solid investment for any MMA enthusiast.

    Marcus Lee – May 1, 2025

    This jockstrap is a must-have for MMA fighters. The Diamond MMA Quad Strap Jock offers unparalleled support and comfort, which is crucial during sparring and competitions. The design is innovative, and the quality is top-notch. It’s a bit pricier than other options, but the performance justifies the cost. Definitely worth it for serious athletes.

  12. Rated 4 out of 5

    Sarah Bennett – May 1, 2025

    I’ve tried several jockstraps for MMA, and the Diamond MMA Quad Strap Jock is by far the best. The additional straps provide excellent support without compromising on comfort. It’s lightweight and breathable, which is great for long training sessions. The only minor issue is that it runs a bit small, so consider sizing up. Overall, it’s a fantastic product that I would recommend to any fighter.

    David Nguyen – May 1, 2025

    The Diamond MMA Quad Strap Jock is an excellent piece of gear. The quad strap system is innovative and offers superior support and stability. It’s well-made and feels durable, which is important for MMA. The fit is snug but comfortable, and it stays in place even during the most intense movements. It’s a bit on the expensive side, but the quality and performance make it worth every penny.
