Collegiate Trek Tumbler

The flip lid seals tight enough that I tossed it in my bag sideways and not a drop leaked. Double wall insulation kept my coffee hot through a two-hour lecture, and the tapered shape makes it easy to grip one-handed.

The tapered bottom fits my car’s cupholder perfectly, and the flip lid hasn’t leaked once during my commute. Tossed in one of the two straws for iced coffee this morning, and it stayed cold for hours.

The double wall insulation actually works—my coffee was still hot after my two-hour morning lecture, and the tapered base fit perfectly in my car's cup holder. The flip lid snapped shut securely, and having two straws included was a nice bonus I didn't expect.
