How does period swimwear work?

Our period swim bottoms have a triple-layer gusset that absorbs your flow and locks in leaks, in and out of the water. And when you throw them in the wash with detergent, everything releases through the top layer so your swimwear comes out fresh and clean. Your other clothes will be totally fine too, we promise.

Here's how the three layers break down:

Layer 1 is a silky-smooth top layer that sits right against the skin.
Layer 2 is a super absorbent middle layer built with our leakproof tech that holds up to 1–3 tampons worth of blood.
Layer 3 is a waterproof outer layer that prevents any leaks from showing through.
