Customer Reviews
Good protection, comfy enough
I grabbed the Diamond MMA Quad-Strap Jock & Cup System a few weeks ago for my krav maga classes. Setup was pretty easy, just took a minute to figure out the straps. It actually stayed put really well during drills, which was a nice change from my old one. Felt secure and didn't bother me much, which is saying something for a jock strap. Definitely happy with it.
Solid gear, few issues
I bought the Compression Shorts with Cup Pocket and the Diamond MMA Athletic Cup. The quality of the materials felt really good, and the cup stayed put during sparring, which was a big plus. Delivery was pretty standard, took 6 days to get to my place. My only minor gripe was that the sizing chart seemed a little off for the shorts; I probably should have gone up one size. Still, overall happy with the purchase, it's a solid piece of gear.
Pretty good cup
Needed a new Athletic Cup for my martial arts class. Ordered it online, it came pretty quick, like in 5 days. It fits my compression shorts well, feels way better than my old one. No problems, just a good cup.
Good value overall
I needed a new cup system for training and found Diamond MMA. I signed up for their newsletter and got a 10% off code, which helped with the total. The Diamond MMA Quad-Strap Jock & Cup System wasn't cheap, but with the discount, I felt like I got good value for a premium product. Shipping took about a week to get to me in Oregon.
Impressive groin protection
I ordered the Diamond MMA Quad-Strap Jock & Cup System a few weeks ago for jiu-jitsu. The ordering process was straightforward on their website, and tracking updates were clear. It arrived within the estimated 5 business days. The system itself is well-designed; the quad-strap really keeps everything secure, more so than other brands I've tried like Shock Doctor. The cup didn't shift at all, even with a lot of movement. Washing the compression shorts was easy too. This gear definitely feels like it's built to last and provides serious protection. It gives me a lot of confidence during training, which is worth it.
Reliable gear as always
This was my third purchase from Diamond MMA. I've used their gear for a while, mostly the compression shorts with the cup pocket, and I needed a new pair of the Compression Shorts with Built-in Cup for my hockey season. Shipping was pretty quick, got to me in about 4 days here in Boston. The quality is consistently good, sturdy stitching and the cup fits perfectly in the pocket without shifting around. It's why I keep coming back, even though they're a bit pricier. You know what you're getting, and it holds up. My previous pair lasted ages through a lot of abuse.
Always reliable protection
This was my third order from Diamond MMA, this time for the Youth Jockstrap System for my son. I've bought the adult Quad-Strap before, and the quality has always been consistent. They shipped it out quickly, and it arrived in California in 4 days, just like my previous orders. It's comforting to know I can depend on them for good protective gear that holds up. That's why I keep coming back.
Decent protection
Got the Diamond MMA Groin Guard. Fit well. Shipping was average. Did the job during training. No complaints.

Hey guys, thinking about grabbing a Diamond MMA cup. Does anyone know if their military discount is easy to get? I'm active duty and want to make sure I can actually use it.
quick question about sizing for the compression shorts with the cup pocket. do they run true to size or should I size up/down?
hey, anyone here use the diamond mma cup for BJJ? is it actually comfortable for ground work or does it feel bulky?
Anyone know how long shipping usually takes for Diamond MMA? I'm in NYC and need a new cup before my next sparring session, which is in like a week and a half.
