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.

Perfect for lighter days

I use this on the days leading up to and on the tail end of my period. Lasts the whole day and excellent for doing sports in. Can't emphasize enough how happy I am with all of my Aisle products.

Reintroduction to thong life

I haven't worn a thong is many years, but this is the most comfortable underpant I now own. Which is almost a bit of a bummer since I would only wear it during my period. I wish you made a non period version and I would buy Oh So Many!!!!!

Runs small

I think these would be incredible for light days, but unfortunately it came fitting extremely tight so can’t wear them :( Because I couldn’t try them, I rated everything a “3” right in the middle.
