The tapered shape fits perfectly in my car's cup holder, which was a pleasant surprise for a tumbler this size. Ice was still intact after a few hours, thanks to the double wall insulation. The included straws are a nice bonus too.

I was skeptical about the leakproof claim, but after tossing it in my bag with ice water, not a single drop escaped. The double wall insulation keeps my drink cold for hours, even on a hot afternoon.

The tapered bottom fits my car’s cup holder perfectly, which is usually a dealbreaker for me with tumblers. Filled it with ice water before a hike and the double wall kept it cold for hours, plus the flip lid didn’t leak a drop in my bag.
