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.
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.
Great product, comfortable, good quality and super absorbent
First time trying Aisle but I'm liking these more than my period underwear from other brands! The insert in the Boost panties is absorbent and gives me extra security on heavy days. My older period underwear has started pilling so I'm hoping I won't have that issue with these. Fingers crossed the quality stays consistent over time!

I love these! They feel like everyday hipster undies, and unlike another brand of period underwear I have tried, they don't stink when full of blood. Very pleased

The best period underwear! So comfy and absorbent! I wear these right when my period starts and I’ve only bled through once (because I was stress testing the booster). I was impressed with how much flow it could hold before it bled through both the booster and the underwear. It lasted till late afternoon before I had to change into different underwear. If that was a pad, I would have had to change it at least once or twice by then AND my underwear would have been stained. Go buy these if you haven’t yet!

Really happy with these! Love having the removable liner. On heavy days the liner fills up by the early afternoon, so i pull it out and use the just the panty absorption for the remainder of the day. They fit great and I love the feeling of cotton on my skin. Will be buying more!
