Collegiate Trek Tumbler

The tapered bottom fits my car’s cupholder perfectly, and the flip lid hasn’t leaked once in my bag. Two straws is a nice bonus, especially since I always lose one.

The double-wall insulation actually works—ice was still clinking around after a three-hour drive, and the tapered base sat snug in my car's cup holder the whole way. Flip lid never leaked once, even when I tossed it sideways into a bag.

Took this to a tailgate and was pleasantly surprised how the tapered base sat snug in the cup holder, no wobble. The double wall kept my drink icy for the whole game, and the flip lid never leaked once when I tossed it in my bag.
