Kolegiacki kubek termiczny Trek

Tossed this in my car's cupholder on the way to class and it didn't budge, even around sharp turns. The double-wall insulation kept my coffee hot through a two-hour lecture, and the tapered bottom is a small thing that makes a huge daily difference.

The flip lid seals tight enough that I tossed it in my backpack on a bumpy bike ride and not a drop escaped. Double wall insulation kept my coffee hot through a two-hour lecture, and the two straws are a nice backup for when the first one wanders off.

The tapered bottom fits my car’s cupholder perfectly, which is rare for a tumbler this size. I’ve knocked it over twice already and the flip lid held tight with zero leaks, and the double wall keeps my coffee hot through my whole morning commute.
