Get yourself a mug that wont ever leak, even on your most extreme adventures. Our NeverLeak technology uses a unique 3-position lid that rotates open for easy sipping, then locks tight when closed. Its also outfitted with thicker-than-usual steel for durability and QuadVac insulation for better thermal protection. Thoughtful features like the grip wrap with a finger loop flattens to fit inside your pack and the lid fully disassembles for a deep clean.
