Collegiate Trek Tumbler

The tapered base fits perfectly in my car's cup holder, and the flip lid hasn't leaked a drop in the month I've been using it. Double-wall insulation keeps my coffee hot through a full morning of classes.

I’ve knocked this over twice already and not a single drop spilled thanks to the flip lid, which is a huge win for my desk setup. The double wall insulation keeps my coffee hot through my whole morning lecture block, and the two straws are a nice backup when I inevitably lose one.

This tumbler’s tapered base fits my car’s cup holder perfectly, something most bottles get wrong. Double wall insulation kept my iced coffee cold through a two-hour lecture, though the flip lid did leak a tiny drop when I tossed it in my bag sideways.
