Fellow® Carter Cold Tumbler

The straw lid actually seals tight enough that I can toss this in my bag without worrying about leaks. Ice from my morning coffee was still rattling around at 3pm, which I did not expect.

The straw lid actually seals tight enough that I tossed it in my bag sideways and nothing leaked. Ice cubes were still rattling around four hours later, which never happens with my old tumbler.

Took this on a 6-hour drive and my iced coffee was still cold at the end with ice cubes barely melted. The straw lid seals tight enough that it didn't leak in my bag, and it fits my car's cup holder without wobbling.
