I've been sipping my tea for over an hour and it's still pleasantly hot—the double-wall insulation really works. The 12oz size is perfect for my daily commute.

The 12oz size fits perfectly in my bag's side pocket, and the double-wall insulation actually works — my tea stayed warm through a whole afternoon of errands. The lid seals tight too, no leaks so far.

Filled it with coffee at 7am and it was still warm at lunch, which I honestly didn't expect from something this small. The 12oz size fits perfectly in my bag's side pocket without leaking.
