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!

Very comfortable

The fit and shape are really nice, especially for when I’m feeling bloated. It feels like a quality garment, and it looks really nice!

Comfortable!

Ooo these ones were the ones I found to be a little lower than I like! I wear a lot of high waisted things so it doesnt really match up, but still a great option and very comfortable! Didn't get to fully test them yet

So cute!

I wanted something different than the brief. I absolutely love the low rise! I like the low rise because it’s less pressure on my abdomen when I have bloating or cramping. They are super soft with high absorbency and wear on my heavy days. Absolutely love. Thanks Aisle 🤍

Great product!

Comfy and absorbent, just need to change the boost insert more often when I have more flow.
