Like your toughest outdoor gear, this mug is built for performance. It features a unique 3-position lid that rotates open for easy sipping, then locks tight when closed. It’s 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.
