The folks at Levi's should stick to dungarees, because they don't seem to be able to make underwear. I bought some Levi's boxer briefs a few months ago, and I have been meaning to throw them away since week one. I don't know why I don't think of it until I'm wearing the damned things, but I don't. I forget all about them and wear them over and over and experience the same problems over and over. I'm an idiot.
These briefs are cut in a way that after you have been wearing them a few hours the short leg part curls up and starts to constrict the scrotum and chafe the insides of the thighs. And if that weren't bad enough, the back end simply will not stay out of the gluteal cleft. The most uncomfortable undershorts ever is what they are.
And another thing. The slit in the front that let's you urinate without pulling down your shorts is horizontal instead of vertical and is practically unworkable without wetting yourself.
