Owala SmoothSip Slider 20 oz Insulated Stainless Steel Travel Tumbler — Leakproof Slide-Top, Keeps Drinks Hot or Cold

The Owala SmoothSip Slider is a 20-ounce stainless-steel travel tumbler with a leakproof slide-top spout and double-wall insulation for all-day hot or cold beverages.

Compact, comfortable, and built for real-life use, this reusable coffee cup blends a smooth sipping experience with dependable temperature retention. The seamless SmoothSip Slider spout minimizes splashing and creates a soft, natural flow while the leakproof sliding lid gives confidence when tossing the cup into a bag or car. Constructed from stainless steel and finished BPA-free, it balances ruggedness and everyday comfort for commuters, students, and anyone who drinks on the go.

How does the SmoothSip Slider stop leaks and spills?

The slider mechanism locks the spout closed to prevent liquid escape, while the low-profile lid design reduces sloshing. When the slider is open, the spout forms a smooth, contoured opening for controlled pours and sips.

• Slide-top locks down for a fully sealed cup when closed
• Seamless spout design prevents splash-back while drinking
• Compact lid profile fits under most car cup holders and cabinet shelves

Will this tumbler keep my drink hot or cold?

Yes — the tumbler uses double-wall vacuum insulation to moderate temperatures for hours. Expect hot beverages to stay warm for several hours and cold drinks to remain chilled much longer, making it versatile for changing daily schedules.

• Double-wall insulation helps maintain beverage temperature
• Rated to keep drinks hot for hours and cold for extended periods
• Stainless-steel interior avoids flavor retention from prior contents

Is the Owala SmoothSip Slider easy to clean and maintain?

Care is straightforward: hand wash the stainless-steel cup and place the lid on the top rack of most dishwashers. Removable components and a simple sliding mechanism make it easy to rinse, so you won't struggle with trapped residues.

• Cup recommended for hand washing to preserve finish
• Dishwasher-safe lid for quick cleaning convenience
• BPA- and phthalate-free materials for safer contact with beverages

What size and fit should I expect for daily use?

The 20-ounce capacity is a balanced choice for morning coffee or iced drinks without being bulky. Its slim, ergonomic shape fits most car cup holders and is comfortable to hold for commuting, desk use, or walking around town.

• 20-ounce capacity for single-serve coffee or generous iced drinks
• Slim profile designed to fit standard vehicle cup holders
• Ergonomic body contours for a secure one-handed grip
