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?

Our specially engineered lining combines super-absorbent Truetex™ technology with a leak-proof lining that absorb 4 tampons worth of fluid. Use the removable booster for an additional 4 tampons of absorbency.

No detectable levels of PFAS have been found in our underwear, based on a detectable limit of one part per million.

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

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.

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.

Gets better and better

This is the 3rd time I've ordered the equivalent oroduct. Lining on this one is the most comfortable. It doesn't feel bulky, but works great!

Best Period Underwear Ever!

The title says it all! I've been using period underwear since the moment they were available. These are by far the best ones I've used. Easy to clean, removable extra absorption, that actually stays in place. Fit is excellent and they look great.

Super comfortable!

I love these hipster period underwear! I just bought one pair to try them out, but I will be buying more. I love the fabric, so breathable and like wearing normal underwear. They fit very nicely, and they don’t cut in anywhere. The booster is a great idea too for changing with you depending on your flow. Super happy with this product, would definitely recommend!
