Compact size without compromise - life moves pretty fast. You need a travel mug that can keep up with you without spilling your coffee on your outfit. Fortunately, the Pinnacle is designed to be leak-proof despite its compact size. Press the Autoseal button to drink. Release the button to seal. The unique cup shape is available in various colors and fits most car cup holders. The drinking button can be operated with one hand - perfect for on-the-go. The one-piece lid opens fully for easy cleaning and is dishwasher safe - no loose or incorrectly assembled parts. The button lock prevents accidental pressing of the Autoseal button. Please hand wash the painted mug only. Thanks to Autoseal technology, the travel mug seals itself automatically after each sip. The Thermalock vacuum insulation keeps your drink hot for up to 3 hours, making it perfect for your active lifestyle.
