Owala 12 oz SmoothSip Slider Insulated Stainless Steel Travel Tumbler

Product description

Includes one 12-ounce insulated stainless-steel tumbler and a SmoothSip Slider lid that seals completely to prevent leaks.

Constructed from double-wall vacuum insulated stainless steel, the cup maintains hot beverages for up to 6 hours and keeps cold drinks chilled for as long as 24 hours. The SmoothSip Slider features a slide-top spout that creates a smooth drinking edge and helps stop splashes or spills when closed.

Materials are BPA- and phthalate-free. The tumbler is sized to fit comfortably in one hand and most vehicle cup holders. The body should be hand washed while the lid is dishwasher-safe for easier cleaning. The product is backed by the manufacturer’s limited lifetime warranty.

  1. Laura Gonzalez 5/5

    Perfect for my coffee

    The color is even prettier in person. It’s comfortable to use and the lid helps avoid spills. Arrived quickly and in perfect condition.

  2. Luisa f. 5/5

    Absolutely love it

    Very happy with this purchase. High quality, elegant design, pleasant to use, and keeps temperatures well. Color looks better in real life and I use it daily.

  3. The One With The Bookworm and Beauty Enthusiast 5/5

    Owala delivers

    This tumbler really performs—keeps coffee hot for hours and the SmoothSip Slider is genuinely leakproof. I can toss it in my bag without worry. The color is adorable and capacity is just right.

  4. Jia Wei 5/5

    Solid everyday coffee mug

    Very pleased with this Owala. Keeps coffee hot a long time, the SmoothSip opening is comfortable, and the slider seals well so I haven’t experienced leaks. Fits my car cup holder and the lid disassembles for cleaning. Reliable and well made.

  5. Rosemary 5/5

    Excellent travel mug

    Smooth sip indeed—keeps coffee hot for hours and does not leak. Easy to clean and a good-looking, perfectly sized mug.

  6. A. G. 5/5

    Keeps iced coffee cold all day

    Extremely happy with how long it keeps drinks cold compared to other cups I’ve tried. Worth the cost in my opinion. The color is lovely and cleaning is straightforward if you follow instructions. Good capacity too.

  7. Jeffrey 4/5

    Nice cup but quite tall

    Stylish and keeps coffee warm a long time. It’s been spill-proof as long as the lid is fully clicked in. The drink spout is deeper than it looks and can be a bit awkward to scrub. Overall I’d recommend it, though the height may be too much for some.

  8. Jenny J 5/5

    Best travel mug I've used

    My go-to travel cup—completely leakproof and simple to operate. Holds enough for my morning and stays warm for hours. I sometimes forget to close the slider at my desk, but otherwise it’s durable and fits all cup holders. Replacing an older handle-worn model with this larger size and very satisfied.

  9. Sheila’s Honest Reviews 5/5

    Great commuter companion

    I use this for morning coffee and it’s become a favorite. Fits car cup holders and the SmoothSip is comfortable without needing to remove the lid. The lid snaps apart fully for cleaning, and I appreciate the reassuring air release when opening and closing. No leaks so far.

  10. Orla 1/5

    Disappointed — started leaking

    Beautiful cup but it developed a leak after about three months of regular use, which was frustrating.

  11. Meredith 5/5

    My favorite travel cup

    Holds enough tea for a long game or road trip. Easy one-handed use, never leaks, and very pleasant to drink from. Fits cup holders and looks good on my desk. The mouth feels great—so I bought this to try and ended up loving it.
