Trek 隨行杯

The lid seals tight enough that I tossed it in my work bag with coffee and nothing leaked, which is my biggest test for any tumbler. The two straws are a nice touch since I can keep one clean while the other’s in use, and the tapered shape fits my car’s cup holder perfectly.

I've been using this tumbler on my morning commute and it fits perfectly in my car's cupholder, which is a huge plus. The leak-resistant lid gives me peace of mind when tossing it in my bag, and having two straws included is a nice touch.

The handle and tapered shape are nice for the car, but the leak-resistant lid isn't quite as tight as I'd like—a slight tilt and a few drops escape. The two straws are a good touch, though the color-matched one feels a bit flimsy.
