Trek-tumbler

My commute got so much easier now that the cup actually stays put in my car's cupholder thanks to that tapered shape. The lid hasn't leaked once in two weeks of tossing it in my bag, and I love that the outside stays dry even with iced coffee.

Finally, a travel cup that actually fits in my car's cup holder without wobbling. The double-wall insulation keeps my coffee hot for over an hour, and no more wet rings on my desk from condensation.

I’ve been using this cup for my morning commute, and the tapered shape fits perfectly in my car’s cup holder without wobbling. The lid seals tight enough that I can toss it in my bag without worrying about leaks.
