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.

THE ANSWER TO MY PRAYERS

I got them for free as part of a promo… I’m obsessed and immediately buying more for my friends. I religiously use the maxi/regular reusable pads and liners by Aisle and I’m so in love!!

I feel less scared, wearing these.

These look great. And they add that extra layer of protection I need. I'm 46, have a fibroid, and bleed very heavy.

I did bleed an eraser size drop through these boxers. But it was not the emergency, I am trying to prevent.
