Collegiate Trek Tumbler

Tossed it in my bag with a half-full iced coffee and drove over some brutal potholes—not a single drop escaped. The tapered base fits my car's cup holder like it was made for it, and the double-wall keeps things cold for hours. Two straws in the box was a nice surprise.

The flip lid seals tight enough that I tossed it in my bag with zero leaks, and the double-wall insulation kept my coffee hot through a two-hour lecture. Two straws included is a nice bonus, though I mostly use the lid.

The tapered bottom fits perfectly in my car’s cup holder, which is a huge win for my morning commute. I’ve already knocked it over twice and the flip lid didn’t leak a drop, so it’s earned its spot on my desk.
