Spartina 449 Tumbler

Thanks to the double-wall vacuum insulation, this tumbler is designed to maintain your beverage's temperature for several hours. While exact times vary based on the ambient temperature and how often you open the lid, it is well-suited for keeping coffee hot during a morning commute or iced water cold throughout a full workday.

The clear lid features a slide closure designed to minimize spills and splashes, making it great for everyday use. However, it is not 100% leak-proof, so we recommend keeping the tumbler upright rather than tossing it into a bag.

Yes, the rubber bottom is a practical addition that provides extra stability on slick surfaces like glass desks or countertops. It also helps prevent that loud clanking sound when you set your cup down.

The included stainless steel straw is durable and reusable. We recommend using a straw cleaning brush with warm, soapy water to ensure it stays hygienic, as the narrow opening can be difficult to reach with a standard sponge.

While the 30 oz capacity is generous, the base diameter is standard for most vehicles. However, if you have a particularly small or unique cup holder, it may be a tight fit.
