Product Description

Introducing the next generation of swim briefs designed to shape your butt like never before! Featuring hidden padding that provides instant volume and definition, our briefs cover your entire backside without the excess fabric found in boxer briefs, boxers, or trunks. Feel confident and comfortable in your own skin!

With Rounderbum H2O, we no longer leave you stranded at the water's edge. Our new swimwear line offers all the technology and innovation you’ve come to expect from Rounderbum. Whether you're splashing in the pool or playing in the surf, our H2O dual-tech brief has you covered. The package technology eliminates the shrinkage effect (you know what we mean), so you can strut out of the water with confidence. Our padded tech is designed to repel water and dry quickly, providing a volume boost to your backside. The comfortable elastic waistband and drawstring ensure a snug fit. After helping you "say goodbye to saggy jeans," we’re now bringing that same confidence to your summer adventures.
