The Mammoth Rover Tumbler is built for life on the go—keeping your favorite drink at the perfect temperature for hours. With double-wall vacuum insulation, it prevents condensation and locks in heat or cold far longer than a standard cup.

Constructed from 18/8 kitchen-grade stainless steel, it’s tough, durable, and won’t leave behind any metallic taste. A crystal-clear lid with a rubber gasket and stopper ensures a tight seal for maximum temperature control.

Finished with a precision laser-engraved HCT logo, this tumbler combines performance and pride in one sleek design.
