NBA Trek Tumbler with Flip Lid

The flip lid snaps shut with a satisfying click, and I’ve tossed it in my gym bag sideways without a single leak. The double-wall insulation keeps my water ice-cold through a full afternoon of errands, which is exactly what I needed.

The tapered base fits perfectly in my car's cup holder, which was a pleasant surprise. I’ve already knocked it over twice with no leaks thanks to the flip lid.

The double wall insulation keeps my drink cold for a decent amount of time, but the flip lid feels a little flimsy and I'm not sure how long it will hold up. It does fit in my car's cupholder, which is a plus.
