rounderbumJonathan Diersing seeks an investor in RounderBum, his line of underwear designed to “enhance male attributes,” in Shark Tank episode 917. Rounder Bum underwear makes men’s bums look rounder through lifting straps, padding, compression or a combination of the three. They also make underwear that gives some “lift” to the front of men’s bodies.

Diersing started the business in 2015 under a manufacturing and licensing arrangement with Rounderwear, a major Mexican underwear manufacturer that has other major brands under its umbrella. The company initially sold men’s boxers, briefs and boxer/briefs, but has since expanded into compression panties for women, compression shirts for men and compression socks.

RounderBum uses several “technologies” to enhance the male anatomy. The “padded tech” adds padding to the bum side of underwear to give a more well rounded look to a man’s butt. Lift tech uses bands to lift saggy butts while Package tech adds more “bulk” to a man’s jewels. There’s even Gravity tech that features a “free-fall pouch” for the package. Compression tech clothing provides support and a slimming effect.

The underwear isn’t cheap at $20-$25 per pair. All RounderBum products are readily available on Amazon. Diersing has the product in several small, mom and pop type men’s shops too. He likely wants a Shark’s help getting into more retail locations. Will a Shark round out a deal for this one?
