Customer Reviews
Consistently great protection
Another order from Diamondmma, and it was just as solid as my previous ones. I picked up another Quad-Strap Jock & Cup System for my son. Shipping was quick, arrived in 4 days. The quality is always there, which is why I keep coming back. It's comforting to know what to expect.
Absolutely love their products!
I got the Youth Jockstrap System for my son, and it's fantastic! The protection is clearly superior, and he says it's actually comfortable, which is a huge win. The material feels really high quality. Shipping was fast too, got it in just 3 days. I'm so happy with this purchase, it's definitely worth it!
Good gear, quick delivery
I ordered the Diamond MMA Groin Guard and a pair of Compression Shorts with Cup Pocket. The website was easy enough to navigate, no issues finding what I needed. I placed the order on a Monday, and it arrived by Friday, which was faster than I expected for standard shipping to California. The gear itself feels really durable, a noticeable step up from some other brands I've tried. The cup fits snugly in the pocket, doesn't shift around during movement. I had a question about washing instructions, and their customer service responded to my email within a few hours, which was pretty good. Overall, a smooth purchase.
Decent value, good cup
I was looking for some good protection that wouldn't break the bank. I grabbed the Diamond MMA Athletic Cup during a sale, which helped with the cost. Shipping was free because my order went over 100 bucks, so that was a plus. The cup itself feels very sturdy and well-made. Compared to some cheaper options, it feels like it'll last. It's a solid investment for the peace of mind.

Anyone ordered from them to, like, California recently? Wondering how long shipping usually takes. Need it before my next class.
Quick question about discounts. I'm a first responder, do they have a code for that? And can I combine it with, say, a Black Friday deal if I wait?
What's their return policy like? If the cup doesn't fit right or something, is it a pain to send back?
Are their cups designed to fit in other brands of compression shorts, or do I pretty much HAVE to buy their whole system?
Hey, thinking of grabbing one of their cups. Anyone know how true to size these are? Usually wear a large in compression shorts, should I stick with that for their jock system?
