College Trek Becher

The tapered bottom fits perfectly in my car's cup holder, which is rare for a tumbler this size. The flip lid snaps shut tight enough that I tossed it in my bag without a single leak, and the two included straws are a nice bonus.

Double wall insulation actually works—my iced coffee stayed cold through a two-hour lecture and the ice was still there at the end. The flip lid seals tight enough that I can toss it in my backpack without a second thought. Plus the two straws are a nice backup when one inevitably gets lost.

The tapered base sits perfectly in my car’s cupholder, so I can sip while driving without it wobbling. The double-wall insulation keeps my iced coffee cold through a whole afternoon of classes.
