If you've ever aspired to be Clark Kent's alter ego, these caped Superman underpants are a great place to start. You might not secretly be a kryptonite-sensitive alien, but you can fight crime in these SuperHeroStuff boxer briefs. Whether you choose to wear them over tights is up to you, of course.
The Superman underpants are blue with a yellow band and red crotch area featuring the Superman logo. They undergarments also have a small red cape that covers your bum, with another yellow Superman logo in the middle of it. The cape is attached via velcro, however, so it's removable if you prefer it that way.
The caped cosplaying boxer briefs will make you feel like the Man of Steel himself, and also make a great gift for comic book fans.
