Collegiate Trek Tumbler

The tapered bottom fits perfectly in my car's cup holder, and I love that the flip lid hasn't leaked once during my morning commute. Having two straws included was a nice surprise.

I've had this tumbler for a week now and the double wall insulation really does keep my iced tea cold for hours. The flip lid is totally leakproof which is great for tossing in my bag.

The tapered shape fits perfectly in my car's cup holder, which is a huge plus for my daily commute. I wish the flip lid locked a bit more securely, but the double-wall insulation keeps my coffee hot for hours. Overall a solid, functional tumbler.
