Trek 隨行杯

Took this on a three-hour drive and the tapered bottom actually fit my cupholder without wobbling, which my old mug never did. The handle makes it easy to grab one-handed, and no water ring left on the console.

No condensation ring on my desk anymore, which is the whole reason I switched from my old plastic cup. Holds ice through an entire workday and the handle makes it easy to grab one-handed.

The tapered shape actually slides into my car's cupholder, which my old straight-sided tumbler never did. No condensation ring on my desk either, even with ice water sitting there all afternoon.
