The CamelBak® Tumbler 20oz is perfect for long journeys and amazing destinations. A durable, full powder-coat finish prevents condensation on the outside of the tumbler, while the copper vacuum-insulated stainless steel keeps drinks hot or cold for hours on end. The tumbler lid features tri-mode flow control, and the tapered design allows for a comfortable grip and a perfect fit for most cup holders. A non-slip silicone pad on the base of each vessel grips surfaces to avoid scratches and spills. 10 hours cold, five (5) hours hot. Recommended to hand wash only. 20oz.
