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.

    Super swim short!

    The leakproof swim shorts are very comfortable and fit very well. It is very reassuring to know that accidents won’t happen while at the pool!

    Does what it’s supposed to do

    I bought this because, you guessed it, I want to swim and enjoy the beach while I’m on my period. This particular pair of swim bottoms does what it says. However, I’m perimenopausal and have extremely heavy periods at times. So, they only held up for a couple of hours for me without swimming. I didn’t try swimming in them yet.

    Looks nice but legs too loose

    Look good when I wear them on dry land. Leakproof protection is decent. Disappointed in the fit in the water. I expected them to fit more snugly, like the Dream Short, which I love. Got a medium which is what I need in the waist; comfortable wide waist band. However, the legs are too loose, and when I jump in the water, the legs ride up, making the coverage in front no better than a bikini bottom, which I do not want. I’m constantly tugging the legs back down for discretion. Plus the leakproof liner doesn’t fit snugly. So I wear a leakproof bikini bottom under them for security. Hoping to try again if the style gets updated. Would love to see a board shirt with a snug dream short style liner and looser outer layer.

    Not as Pictured

    These are terribly designed. They have a thick lining in them that makes it look like you are wearing a pair of underwear under the swim shorts.

    Whyyy Knix, why would you design it this way?! Not a confidence booster at all. Super disappointed.
