Collegiate Trek Tumbler

The flip lid seals tight enough that I tossed it in my gym bag sideways and not a drop leaked. Double wall insulation kept my coffee hot through a two-hour lecture, and the tapered bottom fits my bike's bottle cage too.

Fits perfectly in my car's cup holder, which is honestly a game-changer for my morning commute. The double wall insulation keeps my coffee hot for hours, and the flip lid hasn't leaked once even when I tossed it in my bag sideways.

The flip lid really does seal tight—I tossed it in my gym bag with a full iced coffee and not a drop leaked. Double wall insulation kept it cold for hours on a hot afternoon trek.
