Collegiate Trek Tumbler

First day on campus and I already know this is my go-to mug—the tapered bottom fits my car's cup holder like it was made for it, and the double wall keeps my coffee hot through an entire lecture. Tossed it in my backpack with the flip lid closed and not a single drop leaked.

The flip lid seals tight enough that I tossed it in my work bag with zero leaks, and the double-wall insulation kept my drink cold through a full afternoon of classes. The two straws are a nice bonus, too—one stays at my desk, one in the car.

The tapered base fits my car's cup holder perfectly, which is rare for a tumbler this size. It's been in my bag all week with the flip lid on and not a single drop leaked, plus the double wall keeps my coffee hot through my morning classes.
