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.
Our specially engineered lining combines super-absorbent Truetex™ technology with a leak-proof lining that absorb 4 tampons worth of fluid. Use the removable booster for an additional 4 tampons of absorbency.
No detectable levels of PFAS have been found in our underwear, based on a detectable limit of one part per million.
No need to double up for light days and minor leaks, but we do recommend pairing your thong with a cup or tampon for moderate-heavy periods.
The Aisle Thong was designed specifically for light flow needs, so we skipped the booster for this style.
It’s not that complicated - our undies were made to fit into your regular laundry routine. Just rinse out in cool water, then wash and dry with your regular laundry. As with any garment, wash with like colors.
