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.

Loved product but sizing chart was off

I really like the quality of the underwear and they are easy to use and absorbent. I had some underwear from the company back when they were Lunapads and appreciated that they used only cotton in their products, as it is the best for maintaining vaginal pH. I think the newer ones do not use cotton, but they are still good quality fabric and I have not noticed any increased problems with itchiness. The only downside is that I ordered size S based on my measurements in the chart, and after a wash (too late to return, unfortunately), it is obvious that that size is too small for me! They are just slightly too small and I normally wear a size S in underwear, so it might be worth adjusting the range or mentioning that the sizes run slightly on the smaller size. I can wear these, but a medium would have been a lot more comfortable.
