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 undies 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!

Love the low rise!

These were giving me a bit of a wedgie by the end of the day, but I love how low rise they are as someone with a sensitive tummy. I have a light flow so I can easily do without the booster, but it nice to be able to change it out to feel fresh.

Replacing my Thinx

Really like this fit. Happy to find PFAS-free period underwear that hopefully I can keep for more than a few years this time.

Bigger

I bought two, and one is almost 1 inch larger than the other. Luckily she does to me anyway.
