NBA Trek Tumbler with Flip Lid

Finally got a tumbler that actually fits in my car's cup holder without wobbling. The flip lid seals tight enough I can toss it in my bag without worrying about leaks.

The double-wall insulation keeps my coffee hot for hours, which is a huge plus for my long mornings. I do wish the flip lid locked a bit more securely, but it hasn’t leaked on me yet.

This tumbler fits perfectly in my car's cup holder, which is a huge plus for daily use. The double-wall insulation works well, keeping my iced coffee cold for hours. My only tiny gripe is that the flip lid feels a bit stiff to open at first.
