Mammoth Rover Tumbler

Thanks to its double-walled vacuum insulation, this tumbler is designed to keep liquids hot for over 12 hours. For the best results, we recommend pre-heating the vessel with hot water before pouring in your beverage.

The clear lid features a rubber gasket and a stopper to help prevent spills and ensure a secure fit. While it is highly resistant to splashes and minor tips, it is not designed to be 100% leak-proof if tossed loosely into a bag.

Yes, the deluxe powder coating is specifically engineered to resist wear and tear. It provides a durable, grippy texture that stands up well to the bumps and scrapes of daily commuting.

Yes, the vacuum-insulated construction prevents condensation from forming on the exterior. You can set it on your desk or in your car without worrying about water rings or moisture buildup.

The lifetime warranty covers defects in materials and craftsmanship under normal use. If you experience issues with the insulation performance or structural integrity, Mammoth stands behind the product.

The Rover is engineered to fit most standard cup holders. While it is a larger capacity vessel, the tapered base design allows it to sit securely in the vast majority of vehicle consoles.
