FAQ

How do Aisle 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?

You know your flow best! 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 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 period 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 gusset pockets in BASE undies so there's no need to use Aisle Boosters.

So tight, so uncomfortable, and always leaks

These are awful, I had to throw them away. The band is so tight it cuts into me, even when I sized up, it’s like a little corset. And every time I wear it, it leaks and stains my pants half way through the day. Even on lighter days! Liquids less absorb than kind of roll off. Do not recommend.

tight tight tight...and all the fabric in all the wrong places....

Super unflattering and uncomfortably tight. When you are especially sore and uncomfortable at your stomach, you do not want anything that rises and is tight on your stomach!! There is so much fabric up top, and it amounts to a tiny string between your legs...how is that going to do any good and catch what it should?? When it's that time of month and you want to be in some loose comfies, akin to the loosest sweat pants possible, these are the furthest from that feeling. Think tight a$$ latex glove. While their return policy sounds nice and extra...let's be honest...60 days means you may only have 1 or 2 periods to try these out, which is 1-2 days. I was trying to make these work but they irritated me more the more I wore them and the damn return period closed quick. I'd rather have PFAs than deal with these suckers.

VERY small!

This style is not true to size and runs considerably smaller than other styles. I would recommend sizing up at least one size. The material is nice though!
