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.

I bought 2 for the heavy days and they work perfectly. Snug in all the right places and I don’t have to worry about leaking.

No notes whatsoever. I bought them to sleep in and I just keep wearing them throughout the day.
