Stanley Quencher ProTour Tumbler

Yes, the flip straw lid is designed to be leakproof when properly closed, making it safe to toss into a gym bag or backpack without worrying about spills.

The base is tapered specifically to fit most standard vehicle cup holders, despite its large 40oz capacity. However, if you have a non-standard or unusually small console, it is worth double-checking your specific measurements.

Yes, the entire tumbler, including the lid and straw, is dishwasher safe. This makes cleaning straightforward, though hand washing occasionally can help maintain the finish over the long term.

The vacuum insulation is rated to keep hot beverages at temperature for up to 11 hours. For the best results, we recommend pre-heating the tumbler with a splash of boiling water before adding your coffee.

Yes, the straw is fully removable, which allows you to clean it thoroughly with a straw brush or run it through the dishwasher.

While it is excellent for cold drinks—keeping ice frozen for up to 48 hours—it is also fully insulated for hot liquids. Just be mindful that the flip straw mechanism is designed for sipping, so use caution with very hot liquids.
