This is a VERY niche product . . . but there are at least a few guys out there who WISH they'd had it back when their kids were babies. It's called FridaBalls. And it's a pair of men's boxer briefs with a REINFORCED CROTCH.
Why? So when you're wearing your baby in a baby carrier and his legs are flying, you won't be in horrible pain when one inevitably whacks you in the junk. They cost $28 for a pair.
