Period Underwear (Bikini)

Regular price $34.00

Save 10% when you buy any three (3) zero waste period products!

Tired of buying pads and tampons every month, just to throw them in the trash? Over a lifetime, this adds up to somewhere between 5,000 and 15,000 pads and tampons.  Yikes.

That's why we love period underwear. Use them on their own or as a backup to a menstrual cup, period undies are one of our favorite sustainable essentials.

We've chosen Saalt brand because their designs are thinner than others we've tried, so you'll never feel bulky or uncomfortable. The gusset (aka the crotch) quickly absorbs wetness, keeping you dry and comfortable longer.

If you're like us, you'll be tempted to wear them even when you're not on your period!

Each pair of undies is about as absorbent as 2-3 tampons.

On the fence? Check out our blog post on the five reasons to switch to reusable period products!

To Use
Wear just like any other pair of undies during your period, without pads, liners, or tampons.

Rinse with cold water after wearing to help avoid staining. Machine wash with like colors on cold (your other laundry will survive, I promise) and hang to dry. We recommend washing in a delicates bag for some extra care. Do not use fabric softener, bleach, or iron.

Was I even on my period?

I love sitting around my house without pants on especially when I'm on my period. These are truly a gamechanger. Highly recommend period underwear.
