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.

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

Very high waisted and very small and tight for a medium. I am normally a small but have to size up for Aisle, and even the medium is tight.

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.
