I use these for running and hiking. They are very comfortable, providing no rubbing. A great quality product.
Purchased for hiking, i am very pleased, purchased more, I am a 33 inch waist and purchased a medium which fitted great
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
Very comfortable, fit well, stay put!
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.
