Voyager Tumbler - Signature

I was skeptical about the leak-proof claim, but after tossing it in my bag sideways with hot coffee, not a single drop escaped. And the double wall vacuum insulation kept that coffee steaming hot for over four hours during my morning commute.

I’ve had this tumbler for three weeks now, and the ceramic lining really does keep my coffee tasting fresh—no metallic aftertaste like my old steel one. The double-wall vacuum insulation is no joke, too, since my morning brew is still warm at lunch when I get distracted.

The button lid works perfectly—no leaks even after tossing it in my bag. My coffee stayed hot for a solid four hours, and the ceramic lining really does keep the taste clean, no metallic aftertaste like my old steel mug.
