  • Why You'll Love It

    Proof-partum panties can hold up to 4 regular tampons worth of blood.

    Changing pads just got well…a lot less necessary. Proof® undies are truly panties with a purpose.

    These ultra-absorbent, leakproof underwear are designed with our patented leak-loc technology. This innovative moisture-wicking system prevents vaginal bleeding and discharge from escaping the underwear. The best part, is they look like “real” undies but act like an absorbent pad. Finally, postpartum protection that makes you feel comfortable and confident. Lose the pads, get the Proof!

  • Details Matter

    The Bikini offers total front-to-back leak protection. Our revolutionary leakproof core spans from the front waistband to the back waistband for complete leakproof coverage.

  • Specifications & Care


    Machine wash your undies in cold water on a delicate cycle. Be sure to use gentle laundry detergents. Do not use hot water when soaking/washing as this compromises the undies’ leak-loc™ technology. Once washed, either hang or lay flat to dry. Never use harsh detergents, softeners, or bleach on your proof® undies. The chemicals in those agents can also compromise our undies leak-loc™ technology.
