Best Martial Arts Groin Protectors of 2025

"I appreciate that this cup does what it’s supposed to do. It offers great protection and is amazing for the price. The fit is pretty good, although I found it a bit bulky for some girdles."

"I upgraded my son’s foam cup as he began catching for baseball, and he can wear it all weekend without discomfort. It functions great for him!"

"I want to warn others that Shock Doctor has changed the product since 2016. The newer version lacks the cool carbon fiber design and feels like a cheap knock-off. It seems they’re not concerned about appearance anymore and keep using old photos, which feels dishonest."

"I've been using this cup for years across various martial arts, including striking and grappling. I wear it to every class, even in Judo, where others often don't. The tuck-under design is crucial for its effectiveness. The waistband remains intact despite heavy use, and I clean it easily with anti-bacterial wipes instead of machine washing. Overall, it's an essential purchase for me."

"I bought this for my son, who is 5'10 and 150 lbs. It fits him well and provides more protection than I expected. It also passed the hard cup test for HEMA sword fighting, which is a relief!"

"As someone who struggled to find a fitting cup/supporter, this one worked out great. It stays in place and protects essential areas effectively, above and below."

"I find the cup very comfortable and it fits just right. It was reasonably priced and delivered promptly. I also appreciate the black color option."

"I started training in Muay Thai and MMA and needed protection. I chose the RDX model over the Black Diamond, and overall, it has been comfortable and protective. I train four times a week and despite regular washing, it's held up well. I'm considering getting another for a break."

"I bought this for my boyfriend who practices jujitsu. The underwear portion fits perfectly, but the cup felt a bit cheap. It worked well for him, but the sizing wasn’t ideal. It kept him secure and protected the goods!"

"I never thought I'd leave a review for something like this, but this cup is really worth the money. I didn't buy the jock strap, just used it with snug boxer briefs. It stayed in place without needing readjustment. I wore it through two 8-hour training sessions with no irritation or discomfort, which is a first for me. Definitely spend the extra money on this; you won't regret it!"

"I use this cup for Krav Maga, where it's essential to have protection. I was initially worried about comfort, but I was pleasantly surprised. The soft elastomer edges are forgiving, and it holds everything in place without pinching. Even when practicing techniques that involve groin strikes, I've felt safe and protected. Overall, this cup has been a game-changer for my training."

"I bought this protector because I needed to shield myself from bees in my area. I wear it under short boxers, and it fits comfortably. It does the job well, allowing me to protect my masculinity as needed. I never thought I'd need something like this, but it's been a great investment!"

"I've been using this cup for over six months in my Taekwondo and Hapkido practices, and I find it very effective. It stays in place during drills, and after a little adjustment, I hardly notice it. I've taken several hits to the groin, and while I feel the impact, there's no long-lasting pain. The initial setup was straightforward, but I need to re-tighten the waist strap occasionally."

"This is the best cup I've ever used! It's comfortable without chafing and fully adjustable. I truly forget I'm wearing it when sparring. The protection it offers is top-notch, making it a great choice for anyone serious about their training."

"I just love how this cup fits! The strapping system is genius; it moves with me and doesn't restrict my motion. I've experienced no shifting during movements that typically cause issues with other cups. It's a bit smaller than what I’m used to, but at 5'10" and 155lbs, it fits perfectly and I appreciate its compact design."

"I found it cheaper on Amazon, and it fits perfectly for my nephew!"

"I was surprised at how comfortable it is; the quality is amazing!"

"This is the best groin protector I've found for my size, no more worries about falling out!"

"I was pleasantly surprised by how well it stays in place during sparring. The removable cup is a great feature for easy cleaning after workouts. I found that rinsing the cup helps with condensation. For my 32-inch waist, the Medium size is perfect!"

"I bought this for additional comfort due to some urologic issues. Visiting my friend with three German Shepherds, I needed something protective. This was exactly what I needed! I felt secure from impacts, and surprisingly, it was very comfortable for a first-time user. The XL size was a perfect fit for my usual 2XL bottoms."

"At first, I had my doubts about its quality given the price, but I quickly realized it was worth it! The fit is excellent, and nothing feels cramped or pinched. It offers great protection against strikes. The stitching seems solid, and it's machine washable up to 60 degrees. I'm curious to see how long it lasts with my 3-4 training sessions a week."

"I really appreciate the adjustable waistband. It's a solid cup for sparring and moving on the mats. Just make sure to use the size chart to get the right fit, but it moves well and is strong where it matters."

"After figuring out the right size, I found this product works great. My 12-year-old fits into the XL, while my 9-year-old fits the L. They needed some adjustments while boxing, but the cup stays in place during training. I suggest wearing loose gym shorts to find the best fit."

"As a fan of RDX products, I can confidently say that this cup is both solid and comfortable. The price and quality have consistently impressed me over the years, and I always recommend RDX to my students for their boxing gear."

“I had to try several brands before finding the right one. I prefer wearing it under my shorts, avoiding the diaper look. It fits well under my Muay Thai shorts, especially the stretchy type. Comfortable and non-restrictive; it doesn't hinder my kicks or movements at all. Perfect for sparring and working with partners who may not have precise aim.”

“I purchased this because I get kicked in sensitive areas during sparring, especially from a spirited 11-year-old. Fortunately, this cup provided excellent protection during our last session when she attempted a surprise maneuver. I can confidently say it's highly recommended!”

“I've been using this groin guard for about 10 months now without any issues. It offers great protection, but the materials feel a bit cheap. It still functions well, although it looks like it’s barely holding together.”

"I used to dread wearing cups, as my sack always poked out the sides. I play hockey several times a week and just dealt with it. But this cup changed everything! It's way more comfortable, and I often forget I'm even wearing it. You don’t need to be exceptionally well-endowed to appreciate this cup; I highly recommend it!"

"I bought this as a gag gift for my husband on Father's Day. Surprisingly, it turned out to be really useful during our son's bedtime routine. My toddler can kick hard, and this cup has been a lifesaver for protection, getting used every night!"

"Initially, I thought the large size was adequate, but after a hit to the groin, I realized I needed more room. I consulted my coach, who advised me to try a different size. This cup is definitely more comfortable, as it allows for space without feeling squished while wearing compression shorts!"
