Trek Tumbler

The tapered shape fits perfectly in my car's cup holder, and the handle makes it easy to grab while driving. The outside stays completely dry even with ice-cold water inside, which is exactly what I needed.

The tapered shape fits perfectly in my car's cup holder, and the handle makes it easy to carry even when full. I haven't tested the leak-resistance fully, but the lid feels secure enough for a daily commute.

The lid seals well enough that I don't worry about spills in the car, and the double-wall insulation does keep my coffee hot for a couple hours. The handle is comfortable, but the tapered base makes it a bit tippy on my desk when I set it down between sips.
