Collegiate Trek Tumbler

The tapered base fits perfectly in my car's cupholder, which is rare for a tumbler this size, and the flip lid hasn't leaked once during my commute. Two straws in the box was a nice touch since I lose them constantly.

The tapered bottom fits perfectly in my car's cup holder, which is a huge win since most tumblers wobble around. The flip lid seals tight enough that I tossed it in my bag without a drop leaking.

The double wall insulation is no joke—my coffee stayed hot for a solid three hours during back-to-back classes. The flip lid seals tight enough that I tossed it in my bag sideways without a single drip, and the straws are a nice backup when I'm in a hurry.
