Wore one pair and they rode up my thighs all-day-long, then bunched up around my thigh. Some of the most annoying pair of boxer-briefs I've ever tried. The entire day was spent pulling the lower portion of the underwear back down my thighs. They stayed-put around my waist and the pocket for your junk was nice, and in fact...so long as they didn't bunch, you didn't even know you were wearing anything.

If they stayed put, I would buy more just because of how light and airy they are...butt alas, they just didn't work for me.

tl;dr - if you are looking for briefs that don't ride up your thighs, then these aren't the ones. The best I've found so far are the Adidas sport boxer briefs (the longer ones. Their shorter ones also ride like the above brand)
