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.

So comfy and absorbs well. I've been very happy with the boost! It's pretty nice having the extra pad to use even on medium/light days for easier cleaning. I love green color too!
