I really like these because I don't like wearing underwear so if I got to wear at least wear some with support. I ordered both the black and white pair,these support your package well. The sizes in the description is not correct, I am 5'9 a 170 lbs athletic build and I know I usually have to order a size up because of my thighs. I usually wear a small but with this cut I thought I would order a size up. I ordered a medium,it didn't fit. I returned them with no problem I liked them so much I exchanged them for a large,they fit but the back is cut so low that every time I sit down the tip of my crack is showing. I could actually use a extra large but I will just deal with it and hope they conform to my body and not shrink when I wash them. So guys if your going to order them I just you size up one and if your athletic size up two sizes.
