What's a trunk? Trunk underwear is a boxer brief that's a little shorter.
It hits at mid-thigh or higher, not longer, and certainly not down to the knees. It offers just a little more coverage than a brief, but not quite as much coverage as a long boxer brief, making it the best of both worlds. And what kind of guy prefers trunks? If you're looking at this page, it could be you! Go get your men's trunk underwear and experience the perfect balance.
