Trek Tumbler

The tapered shape actually fits my car's cupholder, which my old straight-sided tumbler never did. Ice was still rattling around after a full morning at my desk, and the handle makes it easy to grab one-handed.

Took this on a 3-hour drive and the tapered base fit my cupholder perfectly, no wobbling at all. The lid hasn't leaked a drop even when I tipped it sideways in my bag, and I like that it came with two straws so I can swap colors.

The handle makes this so much easier to carry on my morning walk, and it doesn't sweat at all even with ice in it. Two straws included was a nice touch, though I mostly use the clear one.
