Support of a jock with the comfort of briefs. Make sure you buy the right size. If you're going to err, err on the higher side as I did. You can simply wash them in very hot water and then pop them in a drier and they will shrink right to size. Best underwear ever. I have been wearing this brand religiously for years. Really holds your package with care and the ladies love them. BTW, incredible price too. Way cheaper than retail, almost 50% off or more.
