Voyager Tumbler - Signature

The ceramic lining makes a real difference; my black coffee tastes noticeably cleaner and smoother than from my old metal thermos. It also keeps it piping hot for a good four hours on my morning commute.

Finally, a lid that actually seals—I can toss this in my work bag with zero worry, and the ceramic lining keeps my pour-over tasting clean instead of metallic. Hot this morning, still warm by lunch, exactly what I needed.

The push-button lid seals completely even when I toss it in my work bag sideways, and the ceramic lining keeps my pour-over tasting clean instead of metallic. My coffee's still hot at lunch, which never happened with my old steel bottle.
