The Flux classic bikini are soft, stretchy and comfortable. Sustainably manufactured with eco-friendly materials. Each pair of the Flux period pants replace 200+ disposables from going to landfill, reducing your waste by 99.5%. Made from OEKO-Tex Certified Materials which are lightweight and quick-drying.

How They Work:

Flux period pants absorb up to 5 tampons’ worth of liquid, yet they look and feel just like regular undies.

The built-in tech works like this:

1. Top layer wicks moisture away from the surface quickly, to keep you dry

2. Our middle layers absorb your blood and lock in your flow

3. The bottom layer pushes liquid back up and keeps you leak-free

It’s simple. Just wear, wash and reuse.

Blood, Sweat, Whatever.
