Stainless Steel 15oz Leak Proof Insulated Coffee Mug with Handle

Our review of the 15oz insulated coffee mug finds it best for commuters and anyone who needs a reliably leak resistant vessel for hot or cold drinks. The single biggest reason to buy is its combination of the patent-pending OctaLock thread system and magnetic MagFlip closure, which together deliver a secure, spill-resistant lid and controlled sipping positions that make it useful on the go. Build and finish feel premium, and the handle adds real portability for daily use.

Key Features

• OctaLock thread system: The lid offers eight distinct sipping positions and locks precisely so you can set the flow and remove the lid when needed without hassle.
• MagFlip magnetic closure: Neodymium magnets assist in opening and hold the lid open while you sip, and the built-in lock makes the cup 100% leakproof for hot, cold and carbonated drinks.
• BevGuard insulation: Double-walled insulation keeps coffee piping hot or iced drinks cold for hours so beverages maintain temperature on commutes.
• Comfort grip handle: A scratch-proof handle provides a secure carry point and makes the 15oz size easier to transport than many handleless tumblers.
• Dishwasher safe finishes: Most finishes are safe on the top rack, simplifying cleanup for everyday use.

Who It's For

This mug is aimed at people who travel with a hot or cold beverage daily and need reliable leak protection, such as commuters, parents, and office workers. The handle and insulated body suit those who prefer mug-style drinking rather than a narrow bottle.

Those who struggle with complex lids or need an extremely simple one-handed opening may want to consider alternatives, because several users report the lid can be difficult to remove or operate until you get used to the twist-and-lock motion of the OctaLock system.
