Rounderbum is a line of men’s and women’s underwear designed to give flat-bottomed people a boost on their bottom. Rounderbum comes with removable padding to “give more gluteal volume and definition” and in a discreet and comfortable way. Rounderbum isn’t just aesthetically pleasing but they also come in handy for those who play extreme sports and for those who sit for long periods of time. The entrepreneur behind Rounderbum, Jonathan Diersing puts on his best blue suit and pitches his business (with an underwear model) on Shark Tank on January 21.
A typical pair of Rounderbum men’s briefs sell online for $20-$25. Jock straps and thongs, and compression undershirts are also available from Rounderbum, in a variety of designs and sizes. Rounderbum also offers Bum Shaping Panties for women, which retail for $35. It’s too bad the disruptor of shapewear, Spanx founder and guest Shark Sara Blakely doesn’t see this pitch! Will Rounderbum appeal to Daymond John who has already invested in Titin, the compression shirts with removable weights? New episodes of Shark Tank (Season 9) air Sundays at 9pm and 10pm on ABC.
