Stanley has been manufacturing quality eating and drinking apparatuses since 1913, and the Classic Vacuum Camp Mug continues this enduring tradition. Double-wall insulation keeps drinks hot for 2.5 hours, cold for 4.5 hours, or iced for 20 hours. Durable 18/8 stainless steel construction is naturally BPA-free and resists rusting while contributing to the mug's timeless and classic design. Partially-attached handle provides a solid hold while still allowing free hand movement, and the integrated D-ring lets you clip it to backpacks and bags. Leak-resistant flip lid. Dishwasher safe. Volume: 16 oz. Color: hammertone green.
