Collegiate Trek Tumbler

The tapered bottom fits snugly in my car's cup holder, which is a huge win for my morning commute. I threw it in my bag with the flip lid on and not a single drop leaked, plus the two straws are a nice backup.

The double-wall insulation actually works—my coffee was still warm after a two-hour lecture, and the flip lid didn’t leak a drop when it tipped over in my bag. The two straws are a nice bonus, and the tapered shape makes it easy to grab one-handed. Solid buy for campus.

The tapered bottom fits my car’s cupholder perfectly, and after a full day of classes my coffee’s still warm. I’ve even tossed it in my backpack with the flip lid on and not a single drop leaked.
