Collegiate Trek Tumbler

The tapered bottom fits my car’s cupholder perfectly, and the flip lid has survived a full day in my backpack without a single leak. Double-wall insulation kept my coffee hot through a two-hour lecture, which is exactly what I needed.

I was skeptical about the double wall insulation, but it kept my coffee hot for over three hours during a morning tailgate. The tapered shape fits perfectly in my car’s cupholder, which is a nice bonus. Only wish the straws were a little longer for taller drinks.

The flip lid really is leakproof, which saved me when I tossed it in my bag on the way to the game. It fits perfectly in my car's cupholder, though the insulation could keep my coffee hot a little longer. Still, for tailgating, it's a solid tumbler.
