FAQ

How do 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 Thongs work for very light flow, or as backup protection for a tampon or menstrual cup.

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 & prolongs the life of your undies! Just make sure they’re fully dry before reusing. Otherwise machine dry low.

Are BASE underwear compatible with Aisle Boosters?

Our period thongs are not compatible with Boosters.

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!
