Owala SmoothSip Slider 20 oz 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 slide-top spout built for comfortable sipping and reliable temperature retention.

Engineered for daily commutes, office desks, and busy weekends, this reusable cup combines a seamless drinking spout with double-wall vacuum insulation. The SmoothSip Slider lid seals completely when closed to prevent spills, while the contoured body fits most car cup holders and your hand. Constructed from BPA-free stainless steel and backed by a limited lifetime warranty, it’s designed to hold hot beverages warm and cold drinks icy without flavor transfer.

How well does this tumbler keep drinks hot or cold?

The double-wall insulation slows heat exchange so hot beverages stay warm and chilled drinks remain cold for extended periods. Typical performance holds hot drinks for hours and cold drinks much longer, making single-fill outings practical.

• Double-wall stainless steel vacuum insulation
• Rated to keep beverages hot for up to 6 hours
• Cold retention up to 24 hours for iced drinks
• Minimal temperature transfer to the outer surface

Is the SmoothSip Slider really leakproof for travel?

The slider lid is engineered to form a complete seal when the spout is slid closed, which prevents accidental leaks in bags or cars. The mechanism is simple to operate with one hand, and the seamless spout reduces splashes while sipping on the go.

• Slide-top spout locks fully closed to stop leaks
• Seamless spout design minimizes splattering
• Easy one-handed opening and closing for commuting
• Secure lid construction to withstand daily movement

How do I clean and maintain this reusable coffee mug?

To preserve seals and finish, hand-wash the tumbler body and place the lid on the top rack of the dishwasher if needed. Regular rinsing after use prevents buildup, and occasional deep cleaning maintains the smooth spout performance.

• Hand wash the stainless-steel cup to protect exterior finish
• Dishwasher-safe lid for quick cleaning
• Rinse immediately after use to avoid residue or stains
• Replace seals or components under the manufacturer’s limited lifetime warranty if defects appear

What makes the SmoothSip spout comfortable compared to other mugs?

The SmoothSip design focuses on a continuous, rounded spout edge to deliver a pleasant, drip-free mouthfeel. Eliminating awkward rims and narrow openings reduces splashes and makes sipping smoother during stops and starts.

• Rounded, seamless spout for a softer sip
• Wide-enough opening that still prevents spills
• Balanced pour and sip flow for hot and cold drinks
• Ergonomic body shape that fits the hand comfortably
