We've all been there; you mean to take a small, graceful sip from your wide mouth bottle and somehow end up covered in water. Meet your new best friend! Made from flexible silicon the Universal Splashguard has enough flex to conform to the size variations of different brands' wide mouth bottles. The SplashGuard is an insert which provides a smaller drinking hole, blocks the splash, is easily removed for cleaning and is dishwasher safe. Allows for easy filling without removing the SplashGuard.
