Fellow® Carter Cold Tumbler

This thing fits perfectly in my car’s cup holder, which is rare, and the spill-resistant straw lid actually works—no leaks in my bag all morning.

I was skeptical about the "stays cold" claim, but I poured iced coffee in at 7am and it was still chilly at lunch. The cup holder fit perfectly in my car, which is a rare win.

The lid really does lock tight—I tossed this in my work bag without a single drop escaping. My coffee was still warm after a four-hour meeting, which never happens with my usual mugs.
