Insulated 25oz Coffee Mug with Handle and Leakproof Lid - Dune

Our review of the 25oz insulated coffee mug finds it best suited for commuters and anyone who needs a reliable, all-day beverage container. The single biggest reason to buy is its blend of a truly leakproof lid system and long-lasting temperature retention, which makes it practical for hot coffee on the morning commute or iced drinks through an afternoon meeting. The feel of the comfort-grip handle and the built-in silicone sleeve also make it comfortable to carry while protecting the stainless steel body from dents.

Key Features

• OctaLock thread system: The patent-pending eight-position thread lets the lid lock in a specific orientation for consistent sealing and easy reassembly.
• MagFlip magnetic closure: Powerful magnets assist in opening the lid and hold it open while sipping, and the built-in lock makes the lid 100% leakproof with hot, cold, or carbonated drinks.
• BevGuard insulation: Double-walled insulation helps maintain brew temperature so drinks stay hot or cold for extended periods.
• Silicone sleeve: The swappable silicone body sleeve prevents dents and adds grip while also allowing a measure of customization.
• Comfort-grip handle: The scratch-resistant handle is shaped for secure carrying and balances the mug even when full.

Who It's For

This mug suits commuters, remote workers, and travelers who value a leakproof container that keeps beverages at serving temperature. The 25oz capacity is especially useful for those who prefer fewer refills and want a single cup to cover a morning or afternoon.

People who prioritize an ultra-slim profile or the lightest possible travel mug might look elsewhere, as the handle and silicone sleeve add a bit of bulk. Those who need a tumbler without a twist-lock lid should consider a simpler cup design.
