WHY UNDERUN?
I've never been a fan of running without underwear, but then again running underwear wasn't all that nice either. Chafing patches and an uncomfortable feeling just seemed to be part of the deal. At the Rotterdam Marathon, I came across Underun and decided to try it out. Since then I have ordered three pair!

My best running purchase so far! A girlfriend recommended I get this underwear after I couldn’t walk around for a week because of severe irritations around my groin. I now use the briefs and think they’re amazing. Thanks!!!

I live in Spain and because of the hot weather, sweating is a problem…. especially in the summer. My New Balance and Odlo boxer briefs are light, but they stay wet. The Underun boxer briefs are slightly thicker but wick away moisture better so they feel drier and cooler. Highly recommended.

I discovered you at the Rotterdam Marathon. Excellent service! I tried out my Underun thong twice during long walks and now I can’t do without them.

Does exactly what it says. Good stuff. I’m a fan!
