Protective, but snug fit

I picked up the Diamond MMA Groin Guard for Krav Maga. The protection itself is top-notch, really feels secure and durable. Shipping was fairly quick, arrived in about four days. My only minor gripe was the sizing chart; it seemed to run a little on the smaller side for the compression shorts. I ended up needing to exchange them for a size up, which was a hassle, but customer service was helpful with the return process. Overall, happy with the core product's performance for high-impact activities.

Good value on bundle

I was looking for some good protection but also didn't want to overspend. I found a bundle deal for the Diamond MMA Quad-Strap Jock & Cup System with an extra pair of compression shorts. It was a pretty good discount compared to buying them separately. Shipping was free too since my order was over $100. Felt like I got a good deal for professional-grade gear.

Solid gear, quick shipping

I ordered the Diamond MMA Quad-Strap Jock & Cup System a few weeks ago. The ordering process was straightforward on their website. It shipped out pretty fast, I think it took 3 days to reach my place in Texas. The gear itself feels really well-made, much better than some other brands I've tried. The quad-strap system definitely keeps the cup in place during training, which was my main concern. No issues with rubbing or discomfort even after a couple of hours. I haven't needed customer support, so can't speak to that, but the product quality and delivery were great.

Comfy and secure

Got the Diamond MMA Jock and Cup for my son. He plays hockey and needed something reliable. He said it's way more comfortable than his old one and doesn't shift around. That's a win in my book.

Do their cups fit well in other brands of shorts? Like if I already have some Under Armour compression shorts?

S Stephanie Walker 1 week ago
Yeah, the cup itself fits in most pockets. I use mine with some older Venum shorts all the time. The Diamond MMA shorts just hold it better.

It'll fit, but you'll lose out on the quad-strap system which is what really makes it secure. Just a heads up.

Thinking of finally upgrading to the Diamond MMA system. Is it really worth the price over a cheaper Shock Doctor or something? My current one just isn't cutting it.

D Danielle Martin 1 month ago
Honestly, night and day difference. Had a Shock Doctor before and it always shifted. The Diamond MMA quad-strap keeps everything locked down. Worth every penny for peace of mind.

For sure it is. Especially for grappling, the diamond cup is way more comfortable and secure. You barely notice it.

Hey guys, wondering if anyone knows how long shipping usually takes to like, California? Need a new cup before my next sparring session.

K Karen L. 2 weeks ago
Mine got to LA in about 4-5 days from when I ordered. Pretty standard shipping speeds for me.

Yeah, usually pretty quick for west coast. I think mine was like 3-4 business days. They're not Amazon fast, but definitely not slow boat.

Anyone know if the military discount works with other promo codes? I've got a referral code from an athlete but also qualify for the military one.

H Hannah Robinson 3 weeks ago
Nah, they only let you use one code per order. Had the same thing happen with a holiday sale and my first responder discount. Had to pick.

Yeah, pretty sure it's one code only. Most places are like that.

I'm between sizes for the compression shorts based on their chart. Should I size up or down for a snug fit that won't feel too tight with the cup?

D Daniel Taylor 3 weeks ago
I'd go with sizing down if you want it really snug. They stretch a bit anyway.

Mine felt a little tight at first, but after a wash or two it loosened up just right. I usually go with my regular athletic short size.
