Kinto-matkamuki.

The double-walled stainless steel keeps my coffee hot through my entire morning commute and into the first meeting, which is exactly what I needed. Lid seals tight with no drips in my bag, and the matte finish feels nice in hand.

Six hours of heat retention isn’t hype—my coffee was still steaming at my desk after a long morning train ride, and the lid never leaked once when I tossed it in my bag. The sleek stainless finish also survived a few drops without a scratch, which is more than I can say for past tumblers.

The double-wall vacuum really holds up—my coffee was still steaming after a six-hour train delay, which never happened with my old mug. It’s sleek enough to sit on my desk without looking out of place, and the lid seals tight enough that I stopped worrying about bag spills.
