Very comfortable, I never run in any other underwear now.

Amazingly comfortable and breathable. Looking forward to putting them through their paces.

So comfortable that you forget you’re wearing them. Nice fit, really good quality fabric, love them

Jordan said: #1 Undies!

I bought these in white after reading lots of good reviews. The reviews were right! These are amazing! I wore them hiking and I didn’t have any problems, no chafing, pinching, or any discomfort. I forgot I had them on! They are nice and supportive and keep everything in place while staying cool and not being too tight. A little pricey (mostly shipping to US) but I will probably buy more sometime!

Tested on a 38 mile ultra and I had no chafing for the first time in my life
