Kolegiacki kubek termiczny Trek

The tapered shape fits my car's cup holder perfectly, which is rare for a tumbler this size. I've tossed it in my bag with the flip lid locked and not a single drop leaked, even upside down. The double wall insulation keeps my iced coffee cold through a long afternoon of classes.

I've spilled coffee on my desk more times than I'd like to admit, but this flip lid actually stays sealed when I toss it in my bag. The two straws are a nice bonus, and the double-wall keeps my iced tea cold through an entire afternoon of classes.

The tapered base fits snugly in my car's cup holder, which is a huge win for my commute. The flip lid snaps shut tight and hasn't leaked a drop in my bag, and the double-wall insulation keeps my coffee hot for hours.
