Owala insulated stainless steel travel tumbler 20 oz — Out of the Blue, leakproof slider lid & double-wall vacuum

The Owala SmoothSip Slider is a 20-ounce insulated stainless-steel travel tumbler with a leakproof slide-top spout designed for comfortable sipping and reliable temperature retention.

Whether you commute, work from a café, or head out for errands, this Owala travel mug is built to keep beverages at enjoyable temperatures while preventing spills. It combines a seamless, ergonomic spout with double-wall vacuum insulation and a durable stainless-steel body, all in a compact 20-ounce size that fits most cup holders. The Out of the Blue finish adds a vibrant look that resists stains and everyday wear.

How does the SmoothSip Slider prevent leaks and spills?

The SmoothSip Slider uses a sliding spout cover that forms a tight seal when closed, stopping liquid from escaping even when the mug is tipped. The lid assembly is engineered for splash resistance while allowing a smooth, unobstructed flow when open. This makes it a practical option for commuting, desk use, or packing in bags.

• Slide-top mechanism creates a secure, leak-minimizing seal
• Seamless spout design reduces drips and improves mouthfeel
• Lid is dishwasher-safe for easy cleaning; body is hand-wash recommended

How long will drinks stay hot or cold in this tumbler?

The Owala tumbler features double-wall vacuum insulation that slows heat transfer, preserving drink temperature for hours. You can expect warm beverages to stay hot for several hours and cold drinks to remain chilled much longer. Performance depends on initial liquid temperature and ambient conditions, but the construction is optimized for typical daily use.

• Double-wall insulation for extended temperature retention
• Designed to keep hot drinks warm for hours and cold drinks chilled through the day
• Stainless-steel interior resists flavor carryover and staining

Is this tumbler safe and easy to maintain?

The materials used are free from BPA and phthalates, and the stainless-steel body resists corrosion and odors. The lid is dishwasher-safe to simplify cleaning, though the manufacturer recommends hand washing the cup to preserve the finish and insulation over time. Owala backs the tumbler with a limited lifetime warranty on manufacturer defects.

• BPA- and phthalate-free materials for daily-safe use
• Dishwasher-safe lid; hand wash the tumbler to protect the exterior
• Limited lifetime warranty covers manufacturer defects

Will this fit my routine and cup holder?

At 20 ounces, the tumbler balances capacity with portability, sliding into most vehicle cup holders and fitting comfortably in one hand. The design is slender enough for commuting yet large enough to hold a typical morning coffee or an extended iced drink. The textured finish and ergonomic shape help with grip and handling on the go.

• 20-oz capacity suitable for standard coffee servings
• Compact profile fits most car cup holders and backpack pockets
• Comfortable grip and durable exterior for everyday use
