ボイジャー タンブラー - シグネチャー

The ceramic lining really does make a difference—my black coffee tastes clean and never picks up a metallic aftertaste. I accidentally left it in the car for four hours and it was still piping hot when I got back.

I’ve been using it for my morning commute and the double wall vacuum insulation keeps my coffee hot for the entire drive, even in cold weather. The ceramic lining makes a noticeable difference—my black coffee tastes cleaner and less bitter than from my old metal mug.

The push-button lid really is leak-proof—I tossed it sideways in my bag and not a drop escaped. Coffee stayed hot for a solid few hours, though I wish the ceramic lining kept the flavor a bit brighter than I expected.
