Standing with your feet together, wrap a soft measuring tape around the
widest part of your lower hip.

Each pair of Aisle Boost underwear comes with a removable absorbency booster that adds an extra 4 tampons of absorbency. It's an innovation that sets these period underwear apart from the rest.
For heavy flow-ers there's no need to change your undies part way through the day, just tuck a Booster in and swap it out as needed.
The fiber that powers our period underwear. One of the most sustainable materials in the world - TENCEL™ Lyocell - is biodegradeable, highly breathable, less susceptible to odour-causing bacterial growth, and absorbs 50% more than cotton.
We developed our own custom blend of materials to create a gusset that's moisture wicking, super absorbent & leakproof without the use of harmful chemical finishes. Our undies keep absorbing, wash after wash after wash.

I’m a recent period underwear convert! There’s no going back! These are super comfortable & soft. I fully trust in their absorbency & coverage. They wash great, especially if you rinse them out well after use.

These period undies are such a game changer. They’re soft, discreet, stylish, comfy, convenient, ethically and sustainably made. What more could I want? I’m really amazed, I figured I’d like them, but I didn’t realize how much. I’m just going about my life, not worrying about my period…?!? Is it even my period if it isn’t a giant pain?? Thank you, Aisle!!

BEST menstrual undies I've ever bought! I've tried several different brands over the years, and these hit the sweet spot of absorption and comfort. No yucky textures or materials that start to get weird after a few washes. LOVE that there are inserts for heavy days. Look forward to getting more next time there's a pattern drop!
