Boost the Absorbency

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.

Made with TENCEL™

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.

Our Tech

Featuring Truetex™ Fabric Technology

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.

FAQ

How do your period undies work?

Aisle undies feature a specially engineered lining that combines super-absorbent Truetex™ technology with a leak-proof lining to keep you dry and feelin’ fly.

How much fluid do they hold?

8X as much as a standard disposable! Our undies absorb 4 tampons worth of fluid on their own, or 8 tampons worth when you wear with the included booster.

Do I need to wear a pad or tampon with them?

Nope! Our undies were built to completely replace pads and tampons. They make great backup protection with tampons or menstrual cups, too.

What does the booster do?

Our undies absorb 4 tampons worth of fluid on their own, but if you need a little extra you can add the optional booster for an extra 4 tampons worth. Just tuck the ends into the slits at either end of the gusset.

How do I wash my Aisle undies?

It’s not that complicated - our undies were made to fit into your regular laundry routine. Just rinse out in cool water, then wash and dry with your regular laundry. As with any garment, wash with like colors.

Great for overnight and heavy flows

I bought my first boost boxer to use overnight since I have heavy flow and would often end up with stains/leaks when using cups or even with the most absorbent overnight pad. I used the boxer with one booster and it worked great! I had no leaks but I did notice in the morning that my flow was spreading to the inner thighs sides of the boxer but even with that happening I did not stain my pants or bed sheets at all. For super heavy flow nights I ended up doubling the boosters, 2 boosters + boxer was the perfect combo, no stains on inner thighs or leaks.

Plus the material is so comfortable and the fit is great, makes me feel more confident/less bloated. I love the boxer so much that I ended up getting a second one to alternate btw night and day :) 5/5 would recommend!

These Make Me Feel So Secure!

I love these for right when my period starts! They offer so much coverage so you don’t have to worry about leaking and the booster can hold so much! They are so comfortable, breathable, and soft - I never feel wet or sweaty down there. The wide waistband also adds another layer of comfort when my stomach is so sensitive because it doesn’t dig in.
