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.

They fit great! They are leak-proof AND comfortable. They don't dig into your legs and I have A LOT of legs to dig into.

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.

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.
