Boelter Brands MLB Travel Tumbler

While the 30-ounce capacity is generous, the base design is tapered to fit most standard vehicle cup holders. However, if you drive a vehicle with exceptionally small or non-standard cup holders, it may be a tight fit.

Thanks to the double-wall vacuum insulation, this tumbler is designed to maintain temperatures for several hours. While performance varies based on ambient temperature and how often the lid is opened, it is highly effective for keeping coffee hot during a morning commute or water cold throughout a game.

To preserve the integrity of the team graphics and the vacuum seal, we recommend hand washing this tumbler with mild soap. Dishwashers can be harsh on the exterior finish and may eventually compromise the insulation properties.

The lid is designed to be splash-resistant for daily use, but it is not 100% leak-proof. It is best to keep the tumbler upright rather than tossing it into a bag where it might tip over.

No, the high-quality stainless steel interior is non-reactive and designed to keep your drinks tasting clean. It will not impart a metallic flavor to your coffee, tea, or water.
