    Super thin

    I used them for the first time on a camping trip when i unfortunately got my period but these were amazing. I’ve tried other leakproof swim from other brands but the gusset was so thick and felt like a diaper, whereas the knix one is super thin the crotch, feel like a regular swim bottom. Didn’t use a tampon with it either and I could wear them for hours. I might’ve wanted an XS instead of S but S still works

    Leakproof swim bottom

    Amazing product! Minimal swell in water and very discrete, all while being effective. I would recommend ordering a size up for a comfortable fit.

    Fit small

    These are good quality but fit small; bought them on sale so they’re final sale :(

    I had bought based on my daughter’s exact measurements, so would recommend sizing up.

    Amazing!

    Order them right before going on vacation and they surpassed my expectations. Went to the pool and the beach with lots of time in and out the water and there was no leaking and the fit is great

    Reduces Camel Toe

    I love this bikini bottom! Because the crotch area is slightly thicker than a regular bikini bottom (leakproof protection), I find that it reduces camel toe and keeps things more private.
