Meet Proof, the New Period Underwear Brand Dedicated to Making a Sustainable Change

Created by the founders of Belly Bandit, Proof is a new leakproof period underwear brand dedicated to reducing waste. For those who aren't aware, tampons and menstrual pads contribute to up to seven percent of the world's landfills.

Proof's silhouettes feature eight different styles like the Everday Undie, Smoothing Brief and Thong, and five absorbency levels ranging from super light to super heavy. Crafted from built-in Leak-Loc™ technology, the undies also cater to six types of leaks such as periods, bladder leaks, sweat, maternity leaks and postpartum leaks, as well as sweat accumulated from a workout. To further help protect our environment, consider switching from tampons or pads to period underwear.

Take a closer look at the different styles above. Head over to Proof's website and shop its current offerings.
