From sunrise to sunset. The strong and durable powder coat finish keeps the 12-ounce CamelBak Horizon Camp Mug looking good on the outside. The double wall vacuum insulation keeps your beverage at the perfect temperature. The tri-mode tumbler lid slides open for variated flow and is spill resistant when closed. A non-slip silicone pad on the base provides a soft landing on surfaces to avoid scratches and spills. Perfect for those early morning tailgates or campouts.
