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?

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!

Comfortable!

These are soooo much more comfortable and breathable than the BASE bikini. I like that there's an insert I can remove on lighter days. The elastic digs in a bit on my butt, but not more than most underwear. Since they're comfy and do the job, these are now my go-to period underwear.
