NBA Trek Tumbler with Flip Lid

The tapered shape is a lifesaver in my car's cup holder, and the double-wall insulation keeps my coffee hot through an entire morning of errands. I also appreciate that the flip lid seals tight enough to toss it in my gym bag without a single leak.

I’ve been using it for road trips and the double wall insulation actually keeps my drink cold for hours, even in a hot car. The flip lid snaps shut tight enough that I can toss it in my bag without worrying about leaks.

The tapered bottom fits my car's cup holder perfectly, which is a huge win for my commute. The double-wall insulation keeps my drink cold for hours, and the flip lid hasn't leaked once even when I tossed it in my bag.
