I absolutely love these briefs! So much that after one day of wearing them I ordered another 3 pack. I went with the XL and they fit me perfect! Im 63 215 lbs. with a muscular build. I have a bigger butt than the average guy from working out is why I need the XL. The material is so nice and they're so comfortable wearing to work and the gym. As youll see in the other reviews yes theres a bunch of tags on the inside back. I cut them all off including the cloth type one with the size indicated on them, no big deal right?!
