Took this on a long road trip and the tapered shape fit perfectly in my car's cup holder. Even after leaving it tipped over in the passenger seat, not a single drop leaked from the straw lid.

Filled it with ice water before a six-hour drive and there was still ice rattling around when I pulled into the driveway. The tapered bottom actually fits my cupholder, which my last tumbler never did, and the straw lid hasn't leaked once in my bag.

I’ve been using this tumbler during my commute and the tapered shape fits perfectly in my car’s cup holder. The double-wall insulation keeps my coffee hot for hours, and the leak-proof lid means I can toss it in my bag without worrying.
