Proof Teen period underwear look and feel exactly like your comfiest undies, but they have built-in Leak Proof® technology designed to help keep you leak-free and feeling dry while on your period. The quick-dry lining pulls moisture away from the body, and technical fibers help inhibit the growth of bacteria and fight odor. The underwear’s Leak-Loc™ edges help keep leaks contained. Plus, Proof Teen panties are machine-washable and reusable, which makes them way better for the environment.
Our Leak Proof® underwear was made to keep you feeling confident and odor-free, no matter what time of the month. A moisture-wicking lining and technical fibers help eliminate bacteria and odor. If you ever feel like your Proof Teen panties need a refresh, add a few drops of vinegar or tea tree oil to your washing machine during the rinse cycle.
Yes! Proof undies can completely replace pads, pantyliners, tampons, and cups. We offer absorbencies that range from super-light to super-heavy (just like tampons!). Our most absorbent panties hold up to 5 regular tampons or 10 teaspoons of liquid. Fun fact: That’s more than the average woman loses during her entire cycle!
Absolutely! Proof Teen undies can serve as a backup for a tampon or menstrual cup to provide extra protection. The most absorbent pairs can hold up to 5 regular tampons or 10 teaspoons of liquid.
Some women believe getting your first period is the right of passage into womanhood. It is an exciting time in your life but it may also be intimidating as well.
With a pair for every flow, you’ll be able to find your Proof™-perfect fit.
