Fluxies are machine-washable and reusable leak-proof underwear — providing a more sustainable alternative to single-use disposable products.
Fluxies period underwear is designed in different absorbencies, from ultra-light to super heavy. Our period pants are built to completely replace single-use disposable products, with maximum comfort in mind.
Every pair of fluxies underwear features our innovative built-in technology — a moisture-wicking top layer to keep you fresh & dry, an absorbent core layer to lock in the liquid, and an outer leak resistant barrier to prevent leaks. Learn more about how period underwear works.

You can wear fluxies period-absorbing underwear for as long as your flow will allow. Every flow is different, and the type of absorbency you choose will affect how long you can wear your fluxies for.
We do recommend you change your period underwear daily, just as you would with regular underwear.
-
Yes! Our period underwear can be worn alone as a complete replacement for pads, tampons or cups. With absorbencies from light to super heavy, you can find a style that suit your flow and can be worn all day, leak-free!
