Introducing the Valhalla Copper Vacuum Insulated Camp Mug. This 14 oz classic camp mug is upgraded with modern style and function. Its double-wall stainless steel construction, featuring copper insulation, keeps drinks icy cold for up to 24 hours or piping hot for 8. A skid-proof cork base and condensation-free exterior add practicality, while the on-trend powder coating delivers durability and a sleek look. The transparent push-on lid with slide closure seals in freshness and flavor. Cork color on lid slider and bottom base varies because of its natural feature.
