Camco's Life Is Better at the Campsite Stainless Steel Insulated Tumblers offer superior heat and ice retention. They feature double-wall vacuum insulation and are constructed of durable, kitchen-grade 18/8 stainless steel. The lid with fully sealing gasket helps prevent heat transfer, meaning your ice stays solid longer or hot drinks stay hot for an extended amount of time. This charcoal-colored tumbler includes a unique pattern featuring a U. S. flag print made of mini RVs.
