How They Work
Our period pants absorb up to 5 tampons' worth of liquid, yet they look and feel just like regular undies.
Our 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
The absorption level is awesome. The cut isn't that flattering but it's comfortable.

Curvy cut underwear
I have a very similar style in another well known brand of period underwear and those have not stood up to these. Flux did everything that pair did not which was retained shape after washing, absorbed well,easy to launder and did not retain any odors. I will be buying more pairs in this style. I have been buying very little disposable s each time I buy a few more pairs, soon I will own enough to rotate quicker to not have to buy them at all. Which should be by next spring.
