FAQ

How do your period undies work?

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.

Do Aisle period underwear contain PFAS?

No detectable levels of PFAS have been found in our underwear, based on a detectable limit of one part per million.

FAQ Image

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?

Our undies were made to fit into your regular laundry routine. Just rinse the gusset in cool water before washing in the machine with your regular laundry. Hang to dry where possible - it saves energy and prolongs the life of your undies!

Super comfy and leak free!

Love these! The high rise is super comfy when im bloated on my period, and the material is stretchy and soft which I love. Plus, the liners work really well, and i love that i have the option of changing out the booster. Really great design overall.

So nice!

These fit so well, they are comfortable and true to size. I would definitely buy more of the style. I can barely notice I’m wearing underwear, compared to how my normal undies fit lol
