Sleek, dark, and mysterious, drinkware inspired by Batman features a glow-in-the-dark logo over a background inspired by the high-tech Batsuit. Crafted from stainless steel with proprietary triple insulation, the Tumbler keeps contents cold and refreshing for 9+ hours and hot for 3. Stays cold even longer with drinks containing ice. Plus, it comes with a sliding, shatterproof lid.
