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.

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.

I’m in shop class 2 days during the week where I’m working on cars for 4 hours straight, it’s hard to work and worry about leaking at the same time so I got these. They work, so well. I have a heavy flow and these did not fail me, even after wearing them all day. It’s so nice to have peace of mind.

Wow!

I’ve bought one of each style of period underwear from aisle cause you never know what fits. Most are comfy and these REALLY ABSorRB. The thick waist band is a bit tight so I recommend getting a larger size if you tend to get bloated during your cycle. But they do stay PUT, no sliding pad nothing!
