FAQ

How do BASE period underwear work?

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

Do your 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?

Our period underwear are designed to be worn on their own, but they make great backup protection for a tampon or menstrual cup too!

How do I wash my Aise BASE undies?

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! Just make sure they’re fully dry before storing or reusing.

Are BASE underwear compatible with Aisle Boosters?

We kept it super simple and streamlined with BASE undies, so you can just put 'em on and go. There are no pockets in the gusset of BASE undies so there's no need to use Aisle Boosters.

Work for bladder leaks.

I was looking for underwear to help with light exercise induced bladder leaks and these fit the bill. Not bulky and good coverage.

Great!

Good for those medium days, maybe not for super heavy flow. Make sure you size up!

Glad I tried it

I love that the waterproof part goes all the way up the back (helps me feel safer sleeping or laying down in them), but the waist isn't very stretchy and makes it a little inconvenient to put on. Once its on it fits great though! Probably won't buy again because I can find something easier to put on, but not mad I have it
