NBA Trek Tumbler with Flip Lid

I’ve been using this tumbler for my morning coffee and the flip lid really does keep it from spilling in the car. The tapered shape fits perfectly in my cupholder, which was a nice surprise.

The double wall insulation kept my drink ice cold through an entire afternoon game, and the tapered shape fit perfectly in my car's cup holder. I was pleasantly surprised that the flip lid stayed secure even after tossing it into my gym bag.

The flip lid seals tight enough that I tossed it in my backpack without a second thought, and not a drop leaked. Double wall insulation keeps my coffee hot through a whole morning of errands, and the tapered base fits my car's cup holder perfectly.
