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.

CARE AND USE 

USE : The leakproof bikini by Proof is perfect for heavy periods. It holds up to 4 regular tampons - that’s 8 tsp! - of liquid, making it perfect for all-day or overnight wear. The bikini is also equipped with front-to-back leakproof protection for extended coverage.

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.
