Water Bottle Mug Vacuum Insulated Stainless Steel 900ml

The FlowState tumbler doesn’t need refilling as often, so you stay refreshed. It keeps your drinks cold or hot for a long time, thanks to its double-wall insulation. You can pick either the 20oz or 31oz size, depending on how much you want to drink. Plus, the slim base fits in most car cup holders, so you can keep it with you wherever you go.

It keeps your water cold for 9 hours and iced for 40 hours, thanks to its special double-wall insulation. Plus, it comes with a clever lid that has three modes: a straw opening that prevents spills and holds the reusable straw in place, a regular drinking opening, and a fully closed top.
