NBA Trek Tumbler with Flip Lid

The flip lid really does keep things leak-resistant — tossed it in my gym bag sideways and not a drop escaped. Double-wall insulation held the cold for a solid few hours, and having two straws included was a nice bonus.

The tapered base fits perfectly in my car's cup holder, which is a huge win for game days. Double wall insulation keeps my drink cold through the whole second half, and the flip lid hasn't leaked once in my bag. It's become my go-to for every road trip.

I’ve been using this tumbler for my morning coffee and it fits perfectly in my car’s cupholder, which is a huge plus. The double wall insulation keeps drinks hot for a solid couple of hours, though the flip lid could seal a bit tighter.
