Collegiate Trek Tumbler

The tapered base slipped right into my car’s cupholder without wobbling, and the flip lid hasn’t leaked a drop in three weeks of daily commutes. I’ve used both straws already—they’re sturdy enough to survive a wash cycle.

The tapered bottom fits my car's cup holder perfectly, which is a relief since most tumblers wobble around. Double wall insulation keeps my coffee hot through a whole morning of classes, and the flip lid hasn't leaked once in my backpack.

The flip lid seals tight enough that I tossed it in my backpack with zero leaks, and the double-wall insulation kept my iced coffee cold through a whole morning of classes. The two straws are a nice bonus, though I mostly use the lid opening.
