With a red lining, blue body, and the classic Captain America Shield symbol the 100% cotton Captain America Shield Blue Boxer Briefs is a great addition to your underwear collection! Captain America's shield is thought to be indestructible, so it makes perfect sense to put it on a fantastic set of underwear! I wouldn't advise using it as a protective cup though, it is more of a theoretical defense. That's okay the because you still love the Captain America Shield Blue Boxer Briefs!
