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.

Love!

Looks cute, fits well, and I really like how full coverage it is. The boost is also great, better than other brands. I now use this booster in other period underwear because those boosters are too short and aren't secure. Aisle will be my go-to brand from now on. I'm 140lbs, more athletic build, I usually wear size 6-8 in pants. Size M fits great. I don't like anything tight and this is comfortable.

Comfort and performance

These are the most comfy period panties I own. They also offer the most coverage and protection. Would recommend. I usually wear them to bed as backup to my cup. I went one size up to make them totally non-restrictive.
