Stanley Quencher H2.0 Flowstate Tumbler

Yes, the base is tapered specifically to fit into most standard vehicle cup holders, despite the tumbler's large capacity.

The lid is designed to be spill-resistant, but it is not 100% leakproof. While the straw opening and rotating cover help prevent major splashes, liquid may still escape if the tumbler is tipped over completely or held upside down.

Yes, the double-wall vacuum insulation works for both hot and cold drinks. However, because it is designed primarily as a straw-based hydration cup, it is generally more comfortable and safer to use with cold or lukewarm beverages.

Yes, the entire Quencher H2.0 is dishwasher safe. You can place the body, lid, and straw in the dishwasher for easy cleaning.

The vacuum insulation is highly effective and will keep water cold for up to 11 hours, or up to 2 days if you use ice.

Yes, the straw is removable for cleaning and can be replaced if lost or damaged. You can purchase standard replacement straws that fit the 40 oz model.
