They really were not joking about it keeping your packer front and center. It's not a negative, just know you really cannot move at least a small packer to the side. I'm a large guy so I got the xxxl and I'm very satisfied with the material (even if it isn't cotton based) and size. The only qualm I have is that the leg bands tend to wander upward making it a bit awkward, but that happens with larger guys sadly. It could probably be fixed by adding a sturder material to the leg bands but, aside from that, the trunks are great
