    • Very comfortable exercise briefs
Size: Medium Number of Items: 1
If a guy has more than a Vienna sausage down there, you know you need some support when exercising. But if you aren't an Olympic athlete, you probably don't want your junk in a vise grip. So these briefs are a happy medium between flopping around commando and way too tight. They're soft and breathable while giving just enough support for running, biking, swimming, etc without feeling like that vise grip. ... show more

    • Order Process Difficulty
Size: Small Number of Items: 1
When ordering this product, it was not very clear to me what size I was going to get. I risked getting a pair because I saw in the picture above that the item was a medium size and runderwear products sell out very quickly. I ended up receiving small sizes, but there was no option when ordering to select a size. They still fit well enough that I’ll use them, and I think the product is great. However, it seems like the order experience through Amazon needs to be improved. ... show more

    • Best running underwear
Size: Medium Number of Items: 1
I’ve usually been fine wearing UA boxers on runs, but these are crazy. They fit really well, and do not chafe at all. I took them out for 8 miles in the late morning and didn’t have to worry about them at all. I was worried about the brief cut at first, but it’s honestly so nice. No riding up, no sticking in uncomfortable places. They have a really nice contoured pouch for your junk, so it feels secure while letting the boys breathe. ... show more
