Collegiate Trek Tumbler

The tapered shape fits my car’s cupholder perfectly, which is rare for a tumbler this size. Double-wall insulation kept my coffee hot through a whole morning of classes, and the flip lid didn’t leak a drop when I tossed it in my backpack.

Was a bit skeptical about the lid, but this thing is truly leakproof—tossed it in my bag with no issues. The double wall insulation keeps my coffee hot for hours, and I love that it came with two straws right out of the box.

The tapered base fits perfectly in my car's cup holder, and the flip lid really is leakproof—I tossed it in my backpack sideways and not a drop spilled. Double-wall insulation kept my drink cold through a full afternoon of classes.
