Stanley The Quencher H2.0 FlowState 30 oz White BPA Free Double-Wall Vacuum Insulated Tumbler

This Quencher H2.0 is generously sized but not oversized with an easy-carry, comfort-grip handle and a narrow base that will fit most cup holders. Long day of meetings rowing class trip out of town. The double-wall vacuum insulation will keep your water cold for 9 hours, hot for 5 hours and iced for 40 hours. And to cap things off, there's an advanced flow state lid that features a rotating cover with three positions, a straw opening designed to resist splashes with a seal that holds the reusable straw in place, a drink opening, and a full-cover top.
