  • Details Matter

    The Brief offers a slim, flexible leakproof core along the center of the undie. Extended coverage comes further up the front and back for enhanced protection.

  • 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.
