I bought the three pack about a year ago. I thought I was the only one chafing this badly. It can be rough as you know. These Runderwear boxer shorts fit quite snug. I'm wearing the medium based on the sizing chart. Don't know that I'd want to wear them all day. They are PERFECT for running though. I have other underwear that I wear that aren't quite as snug, but I'm far more likely to chafe, especially with the summer heat. I began running in my early forties, and I've grown to love it. Unfortunately I chafe easily, all over. It's been tough finding the correct clothing, but Runderwear is the underwear for me! I'm on the site to buy more!

I wanted to love these. They're super comfortable to wear around. But b/c I've got bigger legs than most runners, they still ride up fairly high and therefore don't provide as much anti-chafing protection as I need. Suspect these are 5 stars for all folks with smaller legs but I'm gonna go back to half tights/spandex, which are less comfortable but stay down where they belong.

I recently ordered a pair of the black boxer shorts for a half marathon and wow... I have never felt comfort like it. They do exactly what they say on the packet. No chaffing and so supportive. Everything stayed in place without the constant need to re-adjust myself unlike other branded shorts I have tried. In fact I didn’t even know I was wearing them. It was like going commando but with an invisible support. Highly recommend these to any runner.

Very pleased to find some underwear that has wicking material and prevents chafing. They are very comfortable and ideal for longer runs or hard training sessions in hot weather. Worth the price.

These are expensive but very good in my opinion. Ran the Swansea half marathon in them and got a PB, never felt uncomfortable and they seem to be a decent bit of clothing. Would buy another pair if they weren't so expensive!
