Extra Coverage

Built-in abdomen shield for complete lower-body protection.

Multi-Sport Use

Perfect for MMA, Muay Thai, kickboxing, boxing, baseball, cricket, rugby and more.

Breathability

Moisture-wicking lining and ventilation points keep you cool and dry.

Durability & Flexibility:

There are 3 layers of protective plates within the unit, yes 3. First, a protective hard outer shield capable of the worst. Second, a shock-absorbent bridge foam layer to mitigate shock from multiple directions. Finally, the primary Flex Cup has strategically placed wedges along its edges to flex move with you. This patented design (US Patent Number 10,682,563) allows the cup to be tightened against the body preventing undesired shifting while allowing you to move. There is also a protective plate inside the middle of the belt to provide extra protection for your abdomen.

Convenience & Comfort:

Designed to be worn over or without undies, eliminating the need for you to wear additional compression garments. Surrounding the hard protective plates are breathable, moisture wicking, and comfortable cushions, giving you the feeling of distraction-free freedom. Use the adjustable belts and under-strap to remove the gear anytime.

Adjustability & Stability:

The adjustable middle belt, side belt, and under-strap provide you with ultimate control over the position and tightness of the cup. The 3 adjustable points of enforcement together prevent the cup from shifting during movement or upon impact.

4.8/5

"The A3 is much more reliable than the common brand I used before. I'm way more confident during competition. I actually got hit in the groin during my last fight and was surprised to experience little discomfort. Thank you, War Locker."

Denzel Freeman

"It's super comfortable and strong. My coach snap kicked me to the cup, and I didn't even feel it. The A3 is amazing!"

Ryan Rowley

"I took a kick in this cup, and it didn't hurt! So 10/10, super comfortable and definitely does its job right."

Josue Esquivel

"I love this groin cup for my fighters. I own a MMA gym in NYC called Warriors Nation and I can tell you how handy this cup comes into play when it comes to protecting my fighters both in training and in the cage. It's hard to find a good quality groin protector that can fit comfortably and do its job, and I couldn't be happier to recommend such a great product that not only delivers on what it says it does but also how reliable it is. Our MMA fighter Marcos was so impressed with this groin protector when he first tried it that he threw out all his old ones and wear only his new A3 for every fight! Thank you War Locker!"

Hansel Urena

"The A3 is a great product that is flexible and easily adjustable. It really helps me with my mobility during my training. Super fast shipping too!"

Stephen Oppong

"Check out War Locker for the best groin protector on the market. I'll be wearing them for all my fights and sparring."

Jesse B

"I just tried it on for sparring for the first time yesterday, and it feels like nothing is there!"

Ehab Alrahman

"I have been using this cup for over a month and I really like it. It's quick to get on and it's very comfortable and it actually protects the groin!"

Shaun Seljestad

"Growing up, I experienced all kinds of bad cups playing hockey and lacrosse. With War Locker's A3, it's a complete game changer for mobility and comfort. I've been boxing for about 2 years. I can actually move freely and move side to side easily. For boxing, you really need that. Get yours now!"

Colin Doherty

"There’s really no other product out there like this. It’s flexible, comfortable, and really moves with you unlike most traditional cups. If you’re an active martial artist you know some cut in and become super uncomfortable when kicking or wrestling and moving around, but this bad boy stays in place and with a flexible design gives you WAY more mobility."

Tye Tonkin

"Mine came in, and it's amazing! I don't even notice it during sparring. I took a hard low blow, and I didn't feel it!"

Seth

"I am a huge fan of this cup! My first time trying it during kickboxing sparring was last Wednesday, and it totally lives up to the promise! I had full range of motion and could throw head and spinning kicks like normal."

Jonny Ning

"It's the most comfortable and durable groin protector I've used thus far. Check them out!"

Yu Ji

"I love mine. It really saved me in the clinch today!"

Jadon Moon

"I'm a gym owner and I have seen many other cups bought, worn, and thrown away for another brand. With the A3, however, so far so good! It is awesome!"

Belton Lubas

"Thank you War Locker for the best groin protector I've ever had!"

Elmer Recinos

"The last thing I want to worry about when going into training or a fight is adjusting or the protection of my cup. With the A3 that War Locker has created, it’s the most comfortable and adjustable groin protector in the game! Grab yours NOW."

Frequently Asked Questions

Have lingering questions or concerns?

Click the button below to reach out!

How long does delivery take?

For all US orders, our delivery takes only 2-3 business days because our warehouse is centrally located in Texas, USA.

How do I find the best size that fits well?

Our units are precisely measured in the waist by inches (pants sizes). For best fit, if your waist size is in between our different sizes, please "round up." For example, if your waist size is 30, please select the "30 - 32" size option.

How does the defect-free guarantee work?

If your unit arrives with any clear defects, please simply email us a few pictures of the defect(s) at cs@war-locker.com, and our customer service team will issue you a full refund!

Why is the A3 so expensive?

We spent 5+ years of research and development before obtaining the patent on the product in 2020. Since then, we have only been manufacturing in small batches of a few thousand units each time to ensure our highest commitment to quality over quantity. If you compare our values to all the other high-end products in our category, we are simply second to none. The A3 isn’t cheap, but it’s not overpriced either. Tried and tested with elite athletes in the gym, the product is designed and built to outlast the rest.

How do I clean the unit?

The entire unit is machine washable! However, we do recommend air-dry after each wash for best product longevity.

Can I use the product for other sports?

Yes! The product is sports agnostic. While it’s endorsed by many combat sports athletes, it can be used for any hard contact sports such as baseball, football, and lacrosse etc.

Will there be other new products?

Due to popular demand, we plan to launch both the children's and women’s versions of the A3 groin protector soon. We also have more new products in the pipeline. Please sign up to our email newsletter to stay up to date!
