Proof Leakproof Bikini

The Proof bikini looks like your regular underwear but absorbs up to 8 teaspoons of liquid—including moderate bladder leaks or heavy periods.

Featuring a mid-rise fit and high leg opening, the Bikini offers extended leak protection with Proof's patented Leak-Lac absorbent core technology.

Lined front to back for complete protection, this breathable underwear includes a moisture-wicking top layer keeps you dry, as well as a waterproof liner and outer fabric. The underwear is machine-washable and should be laid flat to dry.

The Proof Bikini can be purchased using your HSA or FSA funds.
