The cup is a little small, but does not move. Fits very well.

Having a hematoma in your testicles isn't fun. Don't know what a hematoma is? Basically internal bleeding/swelling, and I got that from a blunt force trauma injury a couple years back. I've never been the same unfortunately, but I don't let that get me down. I do MMA (techniques/styles include: Muay Thai, Kickbox, Western Box, Kali, Savate, Wing Chun/JKD) and wrestling (techniques/styles include: Grecco Roman, Sambo, BJJ, Judo). With those styles listed it's fair to say I have almost any base covered and when it comes to protection for my injury, I take it very seriously. My first try was the Diamond MMA compression/jock combo. I found these to slip too easily despite there being a drawstring, the back of the shorts always seemed the fall down more than I would like. Then it was multiple shock doctors which didn't last and then it was the RDX cup which wasn't big enough for my beanbag. I have an average size beanbag so I was surprised, but it just didn't have to right shape and I would poke out the sides. Finally, I decided to go back to the Diamond brand because I was very happy with the cup in the first place, and let me say that this is THE BEST. The cup is comfier than ALL the others, and the stitching is super high quality. Everything about the craftsmanship is fantastic and they have a great policy on returns and replacements. Take it from a guy who needs to take care of his beanbag as priority number one, this is the cup to get, well worth the money. Drawbacks? Only thing I can think of is the cup itself, like the act of wearing one. It does restrict movement to a degree, like getting a full pinch of your legs if you were to go take someone's back, but this is the drawback you take wearing any cup, there's a slight setback in mobility, but overall this cup/jock is perfect.

I have several cups and this is probably the best mix of comfort and protection. I have others that are more comfortable but move around more. I have another that offer similar protection but is less comfortable. Overall I am pleased with the product. If you are sticking and kicking, this stays put and protects you where you need it.

This cup fits extremely well. I've been clipped a few times and nothing. No direct hits as of yet, but they will undoubtedly be less damaging than a bare impact. I have strong thick thighs and it is still comfortable for me to use.

Im a slightly above average guy down there, but Im a grower not a shower. I ordered a large and it could just barely cover my pack.
So I have to reorder a bigger size I guess.
