NBA Trek Tumbler with Flip Lid

Finally, a tumbler that actually fits in my car's cup holder without wobbling. The double wall insulation keeps my coffee hot for hours, and the flip lid gives me peace of mind during my commute.

I've been using this tumbler every day since it arrived, and the double-wall insulation actually keeps my iced coffee cold for hours without any condensation on the outside. The flip lid is great for one-handed sipping, and the two included straws are a nice bonus.

The tapered design fits nicely in my car's cup holder, which is a huge plus for daily use. The flip lid seals tight enough that I haven't had any spills yet, though I wish the straws were a bit sturdier. Still, it keeps my drink cold for a good while.
