Yes and no. Anything made in China must be carefully considered as to sizing. Very few of their products will follow what you expect them to be and virtually all of them will run from small to very small. I've worn it-for brief periods as I have a set of yellow shorts and wearing this doesn't show as a typical jock would. The up side is that it functions nicely as jocks are supposed to, this one doesn't err on the size of style over function. Again, if it only were the actual size I ordered....

I have a small waist. 29" so I got a small. They fit rather snug, I wish the pouch was just slightly more open. If you have thick thighs, which mine are fairly muscular, it will be a snug yet comfortable fit. These underwear really plump your butt up! And they are very airy! I'll be buying another pair.

I'm 5'8, 180lbs, 32 waist. I got xxl. They are tight if you have a large package. These are not for men who have a large package more for small package guys. Otherwise everything just doesnt fit inside the front.

This strap is made of a material that looks like gym shorts but stretches nicely. It's a small piece of material cut low and tight so it restrains the goods but stays out of the way of the hip joint. I can't believe for years I've worn those Bike ones that are so scratchy. I wear this one for the usual physical activities like running and lifting but also for less typical things like while turning wrenches when my nads can get all squished between my legs as I lie under the car.

This jock looks really good if you're into it for sexy time too. I got it after seeing naughty videos where the guy was sporting one of these to keep attention farther to the back.

As far as sizing, I usually wear a 33 waist in jeans and a medium in normal undies. I got this Anun jock in both medium and large and prefer the large, which has a bigger waist and leg straps but only by a little bit. Some reviewers have said the pouch is small. I disagree. It does keep the goodies snug against the body but it's stretchy so they're not cramped and I'm looking for containment and stabilization when I wear a jock, so it's just right.

First off, I got this for a vasectomy and it was exactly what I needed. You want a snug fit to ensure everything remains supported and in-place.

You want to at least get 1-2 sizes larger, because you're also going to have to stuff gauze in there to cover the incision site. I recommend buying at least 2 because you'll have some discharge as you heal and you'll want a back-up.

Just FYI, these don't have supportive cups and I didn't need one for my surgery.
