The 530 ml / 18 oz go getter is a double wall vacuum insulated stainless steel tumbler made with pro-grade stainless steel. The wide mouth and ergonomic design of this silhouette facilitates all-day filling and drinking, while the glossy finish adds class to that go getter mentality. The go getter features a clear, push-on spill resistant lid with a silicone sealed slider, a convenient choice for those on the move.
