Bulge Boost Swim Brief Woof Prism vs H2O WAVEFORM Padded + Package Swim Brief

The Bulge Boost is the bolder, more adjustable pick: its inner liner lets you switch between a lifted look and a flatter one, and the single-layer mesh in Fun Mode gives a more natural result. The H2O Waveform adds permanent padding plus a Round Bum effect, so it shapes more of you at once but feels thicker and dries slower. Owners of the H2O rate it around 3.5 out of 5, praising the fit and confidence boost but flagging sizing and a padded, diaper-like look; the Bulge Boost leans on its pouch design and drawstring build rather than padding.

• Choose the Bulge Boost if you want a switchable lift you control and a lighter, faster-drying brief.
• Choose the H2O Waveform if you want permanent padding and a Round Bum effect that need no adjusting.
