The Owala SmoothSip Slider is a 12-ounce insulated stainless steel travel tumbler with a leakproof slide-top spout designed for comfortable, spill-free sipping on the go.

Designed for commuters, desk workers, and anyone who moves between meetings, cars, and errands, this compact mug combines a smooth, seamless spout with double-wall vacuum insulation. It’s built to keep hot drinks warm for hours and iced beverages cold all day, while the slide-top lid eliminates splashes and accidental leaks. Lightweight and ergonomically shaped, it fits comfortably in one hand and most cupholders.

How does the SmoothSip Slider prevent spills during travel?

The slider lid fully seals the spout when closed, creating a leakproof barrier that stops liquid from escaping, even when jostled or tipped. The sliding mechanism is simple to operate with one hand, so you can open it quickly for a sip and close it securely afterwards.

• Slide-top lid that locks the spout closed to prevent leaks
• Seamless spout design reduces splashes while drinking
• Compact 12 oz size minimizes sloshing in moving vehicles

How long will the tumbler keep drinks hot or cold?

Double-wall vacuum insulation preserves temperature effectively: expect hot drinks to stay warm through your commute and cold drinks to remain chilled for much of the day. Performance depends on starting temperature and external conditions, but this design is optimized for everyday use.

• Double-wall insulated stainless steel construction for thermal retention
• Manufacturer guidance: retains heat for hours and keeps cold drinks chilled longer
• 12-ounce capacity balances portability and usable beverage volume

Is the Owala cup durable and easy to maintain?

The tumbler’s stainless steel body resists dents and retains its finish through regular use, while the BPA-free components protect flavor. The cup is hand-wash recommended; the lid is dishwasher-safe for convenient cleaning, and Owala backs the product with a limited lifetime warranty.

• Stainless steel exterior resists damage from everyday handling
• BPA- and phthalate-free materials for safer drinking
• Dishwasher-safe lid and hand-wash body for simple upkeep

What makes the SmoothSip spout comfortable to drink from?

The SmoothSip spout is contoured to follow your lip for an effortless sip without awkward angles or drips. Because it’s seamless and smooth, sipping feels natural whether you’re standing, walking, or sitting at a desk.

• Ergonomic spout contours for a natural drinking angle
• Seamless opening reduces tongue or lip irritation during use
• One-handed slider operation supports multitasking routines
