Owala insulated stainless steel coffee tumbler 12 oz — Black Cherry, leakproof SmoothSip slider, double-wall vacuum

The Owala SmoothSip Slider is a 12-ounce insulated stainless steel travel tumbler with a leakproof slide-top spout designed for comfortable sipping and dependable temperature retention.

Compact and thoughtfully engineered, this Owala coffee tumbler blends everyday practicality with a smooth drinking experience. Double-wall vacuum insulation keeps beverages warm for hours or chilled through the day, while the SmoothSip Slider lid seals completely to prevent leaks and reduce splashes. The 12 oz size fits most cup holders and is sized for your daily espresso, americano, or iced coffee without being bulky.

How does the SmoothSip Slider stop leaks and spills?

The lid uses a sliding spout mechanism that closes securely to block liquid from escaping, even when tipped. Because the spout is integrated seamlessly into the lid, there are fewer gaps where liquid can leak compared with flip-top designs. The result is a travel-friendly cup you can stash in a bag without worrying about dampness.

• Slide-to-close spout locks down for a leakproof seal
• Seamless spout design reduces splash when sipping
• Durable lid materials resist wear from repeated sliding

How long will my coffee stay hot or cold in this tumbler?

Owala’s double-wall vacuum insulation moderates temperature so hot drinks stay warm and cold drinks keep their chill. While exact times depend on starting temperature and ambient conditions, this tumbler is built to maintain heat for hours and preserve cold for most of the day. It’s ideal for commutes, short outings, or steady use at a desk.

• Double-wall stainless steel construction for temperature control

Is the Owala SmoothSip practical to clean and use daily?
