Owala 591 ml SmoothSip Slider Insulated Stainless Steel Travel Tumbler — Pucker Up, Leakproof Slide-Top & Double-Wall Insulation

The Owala SmoothSip Slider is a 20-ounce insulated stainless-steel travel tumbler with a leakproof sliding spout designed for comfortable sipping on the go.

Whether you prefer your beverage piping hot or refreshingly cold, this reusable Owala tumbler combines a seamless drinking spout, double-wall insulation, and a secure slide-top lid to minimize spills and maximize comfort. Built from stainless steel and free from BPA and phthalates, it’s made for everyday use — commuting, desk work, or weekend adventures — while fitting neatly in most cup holders and your hand.

How does the SmoothSip Slider prevent spills?

The defining feature is a sliding spout that closes completely to block leaks. The lid’s design prevents splashes when you walk, drive, or toss the tumbler in a bag, and the smooth, integrated spout removes awkward edges for a pleasant drinking motion.

• Slide-top spout locks down for leakproof transport
• Seamless spout shape reduces splashing and dripping
• Secure lid fits tightly to the stainless-steel body

Will it keep my coffee hot or cold for long periods?

Yes — the SmoothSip uses double-wall vacuum-style insulation to maintain temperature. Expect your hot drinks to stay warm for several hours and iced beverages to remain chilled much longer than a single-wall cup.

• Insulation keeps drinks hot up to 6 hours
• Cold beverages can stay chilled up to 24 hours
• Stainless-steel construction limits heat transfer and condensation

Is this tumbler easy to clean and safe to use daily?

The cup body is stainless steel, and the manufacturer recommends hand washing it while the lid is dishwasher-safe for convenience. Materials are free of BPA and phthalates, reducing exposure to common plastics of concern.

• Stainless-steel cup — hand wash recommended
• Dishwasher-safe lid for simple maintenance
• BPA- and phthalate-free materials for safer everyday use

How portable and user-friendly is the 20-ounce size?

The 20 oz capacity balances generous drink volume with a form that still fits most vehicle cup holders and is comfortable to hold. The SmoothSip’s ergonomic silhouette and leakproof lid make it practical for commuting, travel, or long days at a desk.

• 20-ounce capacity for extended outings
• Ergonomic shape fits comfortably in hand and in most cup holders
• Lightweight stainless steel construction suitable for daily carry

Who is this for? The Owala SmoothSip Slider 20 oz tumbler is aimed at commuters, office workers, parents, and travelers who want a reliable, reusable cup that prevents spills and keeps drinks at a preferred temperature. If you value a comfortable sip, easy transport, and durable materials without single-use waste, this tumbler suits daily routines and active lifestyles. It’s also a good option for anyone seeking a mid-size travel mug with straightforward cleaning and a manufacturer-backed limited lifetime warranty for added peace of mind.
