Collegiate Trek Tumbler

The tapered bottom fits my car’s cup holder perfectly, and the double-wall insulation kept my coffee hot through a two-hour lecture. Two straws included is a nice bonus, though I mostly use the flip lid.

The flip lid is genuinely leakproof—I tossed it in my bag sideways on a bumpy commute and not a drop escaped. Double wall insulation keeps my coffee hot for hours, and the two straws are a nice backup for when I lose one.

The tapered bottom fits perfectly in my car's cup holder, which is honestly rare for a tumbler this size. Double wall insulation keeps my coffee hot through a whole morning of classes, and the flip lid hasn't leaked once in my backpack.
