I bought these for my husband after I "ruined" his old onesies (eg boxer shorts for sports competitions). I found this version from Under Armor and thought it would be the perfect replacement for his old tattered pair. It is great! My husband likes their fit and feel. I plan to buy more in the future. He said the only downside is that he now realizes how flat his ass is because his pants are slipping down because of the silky fabric. However, I'm not against silk ;)
