NBA Trek Tumbler with Flip Lid

The flip lid really locks in place — I tested it with a full tumbler in my bag and not a drop leaked. Double wall insulation keeps my coffee hot for hours, which is perfect for long work shifts. The included straws are a nice bonus too.

The tapered base fits my car’s cupholder perfectly, and the flip lid has survived a few clumsy drops without leaking a drop. Double-wall insulation keeps my coffee hot for a solid couple of hours, which is exactly what I needed for morning commutes.

I've been using this tumbler daily for my morning coffee, and the double wall insulation keeps it hot for hours without any condensation on the outside. The flip lid seals tight enough to toss in my bag without worrying about leaks.
