NBA Trek Tumbler with Flip Lid

I was a bit skeptical about the leak-resistant claim, but after tossing this in my bag with ice water and not a single drip, I'm totally sold. The double wall insulation actually keeps my drink cold for hours without sweating on the outside.

The tapered design fits perfectly in my car's cup holder, and the flip lid has saved me from a couple of spills already. I love that it came with two straws, so I always have a backup when one gets lost.

The double-wall insulation keeps my iced coffee cold for hours, and the flip lid seals tight enough for my morning commute. I just wish the straws were a bit longer for easier sipping while driving.
