NBA Trek Tumbler with Flip Lid

This tumbler fits perfectly in my car’s cup holder, and the double-wall insulation keeps my drink cold for hours. The flip lid seals tight enough that I’ve tossed it in my bag without any leaks.

I was skeptical about the leak-resistant claim, but I've been tossing this in my gym bag daily with zero spills. The double-wall insulation keeps my water ice-cold for hours, even in a hot car.

The tapered bottom fits perfectly in my car’s cup holder, which is honestly a game-changer for daily commutes. The flip lid keeps everything sealed during jostles, and the double-wall insulation means my coffee stays hot until the last sip.
