Collegiate Trek Tumbler

The tapered base fits my car's cup holder perfectly, so I can finally stop juggling it on my commute. Double wall insulation keeps my coffee hot for the whole morning meeting, and the flip lid hasn't leaked once, even when I tossed it in my bag sideways.

The flip lid seals tight enough that I chucked it in my work bag with no leaks at all, and the tapered base fits every cup holder I’ve tried so far. Double-wall insulation kept my coffee hot through a two-hour lecture, which is exactly what I needed.

Tossed this in my car's cupholder on the way to class and it didn't wobble once, thanks to that tapered base. The double wall keeps my iced coffee cold through a two-hour lecture, and the flip lid hasn't leaked a drop in my bag.
