Leakproof swim works in layers

The 3-layer liner absorbs and locks in leaks, whether you're in or out of the water. When washed with detergent, blood releases through the top layer for a fresh, clean suit.

Soft Top Layer

Top Layer

A silky-smooth top layer that feels just like a regular swimsuit.

    Great fit

    I love this bathing suit and was pleasantly surprised at how well it fit! Got my normal swimsuit size. I'd prefer a little more lift but it's very nice for being a one-piece. Got it at a major sale price so even more worth it.
