NFL Trek Tumbler

The tapered bottom fits perfectly in my car's cup holder, and the flip lid hasn't leaked once during my morning commute. I've been using it for game days too, and the insulation keeps my coffee hot for hours.

I've been using this tumbler for my morning commute and it fits perfectly in my car's cup holder. The double wall insulation keeps my coffee hot for over two hours, and the leakproof lid gives me peace of mind tossing it in my bag.

The double wall insulation does its job for cold drinks, but I wish the flip lid stayed open more firmly when I'm driving. It fits in my car's cupholder fine, though the tapered shape means it slides around a bit on flat surfaces.
