FAQ

How do your period undies work?

Aisle undies feature a specially engineered lining that combines super-absorbent Truetex™ technology with a leak-proof lining to keep you dry and feelin’ fly.

How much fluid do they hold?

8X as much as a standard disposable! Our undies absorb 4 tampons worth of fluid on their own, or 8 tampons worth when you wear with the included booster.

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?

It’s not that complicated - our undies were made to fit into your regular laundry routine. Just rinse out in cool water, then wash and dry with your regular laundry. As with any garment, wash with like colors.

LOVE!

I love love love these! I've been using period underwear for years. I've tried Knix, Thinx, and now Aisle and wow Aisle is the clear winner! They are so much more breathable than other period underwear brands. I like the high coverage in the front and back. I do find i notice the seams where the absorbent part is sewn in to the underwear but I get used to it quick

SHOCKED AND IN LOVE

First timer trying anything but a disposable pad or tampon, I was a little nervous as my flow is always heavy and unpredictable. I feel dry and clean and it catches everything! The boost liners also help extend the day. I love these! Need one to last my whole cycle.

Booster is key!

The boxers are really cool! I didn’t use boosters for the first time and on my heavy days, it leaked at night. I learned from mistakes. Now I use one booster for the first day, and I replace it with another booster at night. By the way I wear menstrual cup during entire period.
