Travel mugs provide a convenient way to drink beverages on-the-go, but sometimes that can lead to messy, unwanted spills that disrupt the day. The new Contigo Luxe Autoseal uses a patented technology that completely seals the mug when not in use, making the mug 100% spill-proof to provide confidence against messy spills. Simply press the button to drink, and release the button to automatically seal the mug against spills. The underside of the lid also opens up for easier, more thorough cleaning. The lid can be locked when not in use to ensure the button is not pressed accidentally while being stored or carried. Both the lid and bottle are top-rack dishwasher safe.
