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?

<b>No detectable levels of PFAS</b> have been found in our underwear, based on a detectable limit of one part per million

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.

Great

I normally wear a size xsmall or small for leggings and tops but for underwear I prefer a loser fit and normally opt for medium. I ordered the medium for these and they fit great and I’m glad I didn’t choose a small. The absorbency is great. I wear these when I’m wearing a cup or disc for backup and I wear these on days where my flow is not heavy without a cup or disc. I don’t have to worry about any leaking at all with these.

Comfortable!

Wide, high rise waistband is super comfortable, if perhaps a little thick as it’s a double layer. They tended to run a little smaller than other aisle products, but i sized up 1 and have a generous fit

Super comfy, more absorbent than expected

Love these. Obv they’re not going to be as absorbent as the full underwear options, but they’ve truly been a lifesaver for those lighter days. Had initially bought one pair to try em out and now have 5 since I love these so much.

Very cute

Got these for my bestie and she loves them. They were a little tighter than her size usually is for Aisle products, but not so badly that she would have needed to size up. Very cute too
