MICHAEL LI YUNG TONG said: Unbeatable value for money

I use these for running and hiking. They are very comfortable, providing no rubbing. A great quality product.

Mark Tate said: Excellent underpants

Purchased for hiking, i am very pleased, purchased more, I am a 33 inch waist and purchased a medium which fitted great

Anthony said: 5 star

I've run a 50k ultra marathon in them. With the bits they covered worked brilliant. But need to be a bit longer in the legs. Chaffed on ina thighs where wasn't covered by Runderwear. Probably would of been fine if was a little longer

Helen Williamson said: Very comfortable

Very comfortable, fit well, stay put!

Bruce Craven said: Briefs fantastic

Bought the briefs based on the reviews I'd read and can happily say after a few runs already they are fantastic. Working exactly as intended. You really don't notice you have them on. Thoroughly recommend.
