They fit amazing, which is everything when it comes to zero leaks and good hold. Super easy to wash, and don't stain easy either!
For the perfect fit, don’t take a wild guess — take your hip
measurement! Standing with your feet together, wrap a soft
measuring tape around the widest part of your lower hip.

The fabric for our BASE undies is designed to have a snug fit
that moves with you. If you're between sizes, we recommend
trying the larger size for BASE.
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.
No detectable levels of PFAS have been found in our underwear, based on a detectable limit of one part per million
Our Thongs work for very light flow, or as backup protection for a tampon or menstrual cup.
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.
Our period thongs are not compatible with Boosters.
