The double wall insulation is no joke—my iced coffee stayed cold for hours without a single drop of sweat on the outside. The leak-resistant lid gives me peace of mind tossing it in my bag.

The tapered shape fits my car’s cup holder perfectly, and the handle makes it easy to grab on morning commutes. I’ve left it in the sun for hours and the outside stays completely dry, plus the lid hasn’t leaked a drop in my bag.

I was skeptical about the cupholder fit, but this tumbler slides right into my car's cup holder without wobbling. The handle makes it easy to carry, and the lid hasn't leaked once during my commute.
