Proof was designed with a simple mission in mind: to empower women everywhere to live their best lives without worrying about leaks, and to reduce the amount of single-use plastic waste on our planet.

Proof's most powerful leakproof undie! The Hipster provides the highest level of absorbency and protection for your leaks, while providing modest coverage. Feel fabulous and comfortable with Proof's patented, multi-layer Leak-Loc™ system, which draws moisture away from the body to keep you confident and odor-free.


Outer: 75% Nylon 25% Spandex 

Lining: 100% Polyester 

Lining: 69% Cotton 25% Polyester 6% Acrylate


USE : Even the heaviest of flows have met their match with the leakproof hipster by Proof! Our leakproof hipster absorbs up to 5 regular tampons or 10 tsp of liquid and keeps it locked in the Leak-Loc™ core. Front-to-back leakproof protection keeps you covered, even overnight.

WASH : Machine wash in cold water on a delicate cycle, using gentle detergents. To sanitize and refresh, use a few drops of tea tree oil or vinegar in the rinse cycle of your washing machine. Hand washing in cold water works, too!

Do not use hot water, harsh detergents, softeners or bleach when washing as it may compromise the technology in your undies.

Once washed, hang or lay flat to dry, it normally takes between 6-24hours to dry. For a quicker dry, blot any excess moisture and hang dry.
