Trek 隨行杯

I was a little skeptical about the "cupholder friendly" claim, but it fits perfectly in my car's holder even with the handle. The double wall insulation really works—no sweat on the outside, and my coffee stayed hot for hours.

The lid seals tight enough that I can toss it in my bag without worrying about leaks, and the outside stays completely dry even with iced coffee on a hot morning. The handle makes it easy to carry, and the tapered bottom means it doesn't wobble in the car.

The tapered shape fits well in my car's cup holder, and I appreciate that the outside stays dry while the coffee stays hot. My only small gripe is the lid could seal a bit tighter, but it hasn't leaked on me yet.
