FAQ

How do Aisle BASE period underwear work?

Aisle 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 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?

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

How do you wash Aisle BASE period underwear?

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.

Great PFAS-free option

Came to aisle after realizing they're the only company I can find without PFAS in their garments! Really like this model.

Really like but a bit snug

I love them and think they work great as a backup to my menstrual cup or when I am free bleeding. I usually wear a medium in leggings and other brands of underwear and have never sized up before but felt these were a bit snug and would’ve def sized up

Try other fits if you have a booty

I’m wearing this pair right now. I don’t reach for these pairs the way I hoped I would. I love the smooth gusset, I just wish they would have adapted the existing styles with the BASE gusset. I have to agree with some of the other reviews, these aren’t super stretchy. They definitely fit on the snug side. If you don’t like a cheekier fit, and you have any amount of booty, I suggest not purchasing the BASE line. Both pairs get absolutely swallowed by my ass if I move the wrong way. I need to size up for my next purchase, but

It will only give me hip room for these, not more cheek coverage.

Pretty good though a little tight.

I really love them! Much more comfortable than pads. However, despite measuring myself as instructed, I find the underwear are on the snug side. Wearable, but they are tight enough to give me a bit of a muffin top! Had they been a little more elasticized, this likely would not have been an issue.
