Trek 隨行杯

I’ve been using this tumbler daily for two weeks now, and the leak-resistant lid has survived being tossed in my bag upside down more times than I can count. The exterior stays completely dry even with iced coffee, which is a huge win for my car’s cup holder.

The tapered shape fits perfectly in my car's cup holder, and the handle makes it easy to grab while driving. I love that the double wall insulation keeps my coffee hot without any sweat on the outside.

My commute's a lot smoother now that this tumbler fits right in the cup holder and the handle makes it easy to grab one-handed. The double wall really does keep the outside dry, no more wet ring on my desk.
