Turbo Men's Burger Water Polo Brief

I have a 15-yo diver who was looking for something unique to wear at his diving club. I googled the differences between water polo briefs and swim/dive briefs - that they're more rugged and a less stretchy. That does seem to be the case. They have a double layer of less stretchy fabric. Because of that, out of the package they look a bit bigger than swim briefs of the same size, but on his body they fit really well. And in practice, I can't even tell you how happy he is with his hamburger briefs. Silly kiddo.

In sum: my son is 5'6" and 133 lbs. He got a size 30, which fits him perfectly. He has no complaints about feeling restricted in movement, and the body coverage is good.
