NFL Trek Tumbler

I've been using this tumbler for game day and the double-wall insulation really keeps my drink cold through the entire fourth quarter. The tapered shape fits perfectly in my car's cup holder, which is a nice bonus.

The flip lid is easy to use, but I'm not sure how leakproof it really is—had a small drip in my bag. It keeps drinks cold for a bit, but not as long as I'd hoped. Decent cup for the price, just doesn't wow me.
