I love these long underwear! The material feels great. I've read a few reviews online where people spoke of having issues with the boxer briefs riding up. However, I've had 0 issue with any of my Culprit long boxer briefs riding up. I hesitated with getting these (Disco Bunnies🕺🐰 Long-Cut Boxer Briefs w/ fly), as all they had left was L and I typically sport XL. I dug the graphics and kept lusting over them online. The temptation overtook me and I figured if the L didn't work, I would wash them up and pass 'em along. Well, I'm super glad I bought them because they feel and fit quite lovely (got even raver reviews from my wife). Don't change a thing from this formula, Culprit! Keep the long boxer briefs, keep'em with the fly!!!
