Period Bikinis: Water use, absorption, and functionalityUpdated an hour ago

Our period bikinis and swimsuits feature a technology composed of absorbent layers and a waterproof outer membrane.

• Does blood leak into the water? No. The waterproof membrane and snug-fitting seams prevent menstrual flow from leaking out and keep excess water from entering.
• Does it swell in the water? No. They do not swell or become heavy when coming into contact with pool or sea water.
• Absorption Level: Equivalent to 2 tampons (up to 8 hours of protection).
• Changing After Swimming: You can continue wearing the bikini after getting out of the water unless you have reached its absorption limit or feel dampness.
