Trek Tumbler

The tapered bottom actually fits my car's cupholder, which is more than I can say for my last tumbler. No condensation ring on my desk either, even with ice water sitting there all afternoon.

The handle makes this so much easier to grab on my way out the door, and it actually fits my car's cupholder without wobbling. No condensation ring on my desk either, which was the whole reason I switched from my old tumbler.

Filled it with hot coffee at 7am and it was still warm at lunch, which honestly surprised me. The tapered base slots into my car's cupholder without wobbling, and the outside stays completely dry.
