Coffee stays hot for a solid four hours in this thing, and the outside never gets that sweaty condensation ring on my desk. The straw lid is my go-to for commuting, and it hasn’t leaked a drop in my bag yet.

The flip lid locks in snug enough that I tossed the tumbler in my work bag without a second thought, and not a single drop escaped. Plus, the outside stays completely dry even with iced coffee sweating away inside for hours.

The double-wall insulation is no joke—I poured hot coffee at 7 AM and it was still steaming at noon. The flip lid snaps shut tight enough that I can toss it in my bag without a single drop leaking.
