Collegiate Trek Tumbler

The flip lid seals tight enough that I tossed it in my bag without a second thought, and not a drop leaked. Double wall insulation keeps my coffee hot through my whole morning class, and the tapered base fits my car's cupholder perfectly.

Finally a tumbler that doesn't wobble or spill in the car—the flip lid seals tight and those two spare straws are a lifesaver when one gets lost. Ice still clinking around after a few hours, so the double wall is doing its job.

The tapered bottom fits perfectly in my car's cup holder, which is a huge win since most tumblers wobble around. Flip lid clicked shut and survived a full toss in my gym bag with zero leaks.
