I have a 40" waist and I had some reservations about ordering the XL because it listed the size as 37" - 39", but they fit very well. The straps are not loose and the pouch fits well. I'm average sized and it keeps things exactly where they should be without feeling loose. I think these are fine for men with a larger endowment too. More importantly, they are soft and stretchy, so they are good for every day wear too. I prefer jock straps over briefs or boxers and these work well as an alternative to standard underwear. Honestly, they're more comfortable than most underwear that I've ever worn. I don't go to a gym or do any jogging or running, but I suspect that these are fine for athletic wear as well. Again, everything stays in place, so they should be fine for athletes. Besides the comfort, the narrow waistband is fantastic. It's so much better than other brands with larger waistbands. I don't praise many things highly, but I highly recommend these jock straps both as an athletic supporter and for daily wear. They are just that comfortable. This is now my go-to brand and I will be purchasing these now to replace worn out underwear.

This is my second three-pack. I ordered another the week the first three-pack came. I've worn them exclusively since. The support is a godsend after hernia surgery. But these are quite stylish. I'll probably keep wearing them even when I return to full weight-bearing duty.

I'm 5' 11", 220lbs with a 38-40 inch waist. The XLs fit me perfectly. These jocks offer excellent support and look great. After washing and drying they fit even better. Super comfortable to be worn alone or under clothing.

2(x)ist has always been my favorite brand of underwear. No guessing with size. Your normal size in underwear is what you would order in 2(x)ist. Nice cool comfortable pouch. The straps stay perfectly flat and stay in place all day with no twisting. The waist band and straps keeps their shape after many multiple washings. I have bought multiple pairs of this brand and have not been disappointed once. I hope 2(x)ist keeps this style of jock strap underwear coming for quite some time.

Great jock! Super comfortable. Forget it's even on. Super soft straps that stay and a pouch that fits and feels great. I will be buying more.
