NBA Trek Tumbler with Flip Lid

Took this on a road trip and the tapered base fit perfectly in my car's cup holder, plus the double wall kept my drink cold for hours. The flip lid snapped shut tight enough that I didn't worry about spills when I hit a bump. Two straws included was a nice bonus, too.

The tapered shape fits my car’s cupholder perfectly, which is rare for a tumbler this size. The flip lid seals tight enough that I tossed it in my gym bag without a drop leaking, and the double-wall keeps my drink cold for hours. Two straws included is a nice bonus, too.

The flip lid seals well enough for a desk, but I wouldn’t trust it fully in a bag since it’s only “leak-resistant.” Double wall insulation keeps my drink cold for a couple hours, though not all day like I hoped. Fine for sipping at work, just don’t expect miracles.
