Trek 不倒杯

I've been taking this tumbler to work every day and love that it fits perfectly in my car's cup holder. The double wall insulation really works—no condensation on the outside even with ice water.

No more rings on my desk from sweating cups — the double wall really does stop condensation. The handle makes it easy to grab one-handed when I'm juggling keys and coffee.

The tapered shape fits perfectly in my car's cup holder, and the lid seals tight enough to toss in my bag without worry. No condensation on the outside, so my hands stay dry.
