Bottomless briefs were created as a sexy formation of both a bulge-enhancing brief and a jockstrap. The result? Quite possibly the sexiest piece of underwear that a guy can treat himself (or his playmate) to. Bottomless underwear exposes your bum cheeks, whilst supporting the rest of your package JUST like a brief. They are ideal for many activities; SEX, working out, supporting your bum in tight bottoms and for chilling in hot weather. Bottomless is always better.
