Camco’s Life Is Better at the Campsite Stainless Steel Insulated Twist Top Tumblers offer superior heat and ice retention with a spill-free travel design. They feature double-wall vacuum insulation and are constructed of durable, kitchen-grade 18/8 stainless steel. Featuring a two-piece lid design, a BPA-free lid attachment screws and secures into place for a longer period of heat retention and a no-spill experience. The screw on 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.
