Owala SmoothSip Slider insulated stainless steel travel mug 12oz — leak‑proof, handle & sliding lock

The Owala SmoothSip Slider is a 12oz stainless-steel travel mug with a patented SmoothSip spout, sliding-lock lid, and carry handle for fully leak-proof, commute-ready sipping.

Designed for everyday commutes, desk use, and short outings, this compact insulated tumbler keeps drinks hot or cold while preventing spills in bags and cupholders. Its tapered base fits most vehicle holders, the wide mouth accepts ice and simplifies cleaning, and the handle provides a reliable grab for on-the-go use. Constructed from durable stainless steel and finished with BPA-, lead-, and phthalate-free materials, the SmoothSip Slider balances practical features with low-maintenance care.

How will the SmoothSip Slider perform on a busy commute?

The SmoothSip Slider was built to minimize fuss while traveling. Its sliding lock lid clicks shut to stop accidental openings, and the tapered 12oz body is engineered to sit securely in most cupholders so you can keep sipping during stops and starts.

• 100% leak-proof sliding-lock lid prevents spills inside bags and cars
• Tapered base fits most cupholders for stability during drives
• Lightweight, 12oz capacity reduces the chance of sloshing on bumpy roads
• Sturdy carry handle makes one-handed transport simple

Will it keep my coffee hot or iced drinks cold?

Yes — triple-layer vacuum insulation helps maintain beverage temperature longer than a single-wall cup. While exact hours depend on fill temperature and external conditions, the design slows heat transfer for extended enjoyment of both hot and cold drinks.

• Triple-layer vacuum insulation retains heat and cold efficiently
• 12oz size is ideal for a standard coffee serving or iced beverage
• Wide-mouth opening accepts standard ice cubes for cold drinks
• Stainless-steel interior resists temperature-related wear and flavor transfer

Is the SmoothSip Slider easy to clean and safe to use?

Cleaning is straightforward: hand wash the cup and place the lid in the dishwasher after disassembly. Materials are chosen for daily safety, avoiding BPA, lead, and phthalates so your drinks remain free from these common contaminants.

• Wide-mouth opening for easy hand washing and ice removal
• Lid disassembles for a thorough dishwasher-safe clean
• BPA-, lead-, and phthalate-free materials for safer drinking
• Durable stainless-steel build reduces corrosion and staining

How comfortable is the design for repeated use throughout the day?

The SmoothSip Slider balances compact capacity with an ergonomic profile and a comfortable handle, making it pleasant to hold during long commutes or between meetings. The SmoothSip spout is shaped to guide liquid smoothly, reducing drips and awkward angles while you drink.

• Ergonomic SmoothSip spout designed for comfortable, controlled sips
• Sturdy handle provides a secure grip when walking or carrying
• Compact 12oz size reduces wrist strain compared with larger tumblers
• Slip-resistant finish improves hold when hands are wet

Who is this for? The Owala SmoothSip Slider 12oz is ideal for commuters, office workers, students, and anyone who prefers a compact, leak-proof tumbler that fits cupholders and won’t overwhelm a bag. If you want a durable daily mug that keeps beverages at a stable temperature, prevents spills, and is easy to clean, this travel-ready stainless-steel option is a practical match.
