Trek Tumbler

Finally, a tumbler that actually stays put in my car’s cup holder—the tapered base is a game changer. The lid’s leak-resistant seal has survived a few tumbles on my commute, and the outside stays bone dry even with iced coffee.

I was skeptical about the sweat-free claim, but after a full morning commute with hot coffee, the outside stayed completely dry. The handle makes it easy to carry, and the leak-resistant lid has survived a few minor drops without spilling a drop.

The tapered shape is genius—my cup finally fits in the car holder without wobbling, and the handle makes grabbing it on my way out so easy. Drove an hour with coffee inside and not a single drop escaped past the lid, plus the outside stayed bone-dry the whole time.
