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!

Absolutely Everything!

These are the most comfortable period underwear. I feel so good in them during that time of the month when I feel extra bloated. They fit right and are so cozy.

Perfect

These are perfect for me ! As a fat person, it's really hard to find underwear that fit correctly, and ever harder when it's period underwear, but these fit just right. It's soo comfortable, it's not too tight at all around the belly and since the material is really thin, it feels like I'm wearing regular undies.

I have a moderate flow and I can keep them on for 6+hours during the day or night without any problem. Compared to my past period undies they dry very quickly (~24hrs). It was pretty expensive all in all bc i had to pay the international shipping + customs when it arrived here but I don't regret it at all

Such an upgrade

I had the cloth pads for years and I'm so glad I upgraded! These feel like my regular underwear, I don't feel like I'm wearing a diaper anymore, everything stays in place, and I really appreciate the high waist, it doesn't fold into my cramps when I sit. Easy to swap out boosters on heavy days or leave them out on light ones, easy to wash, these have it all!
