The sleek design fits perfectly in my car's cup holder, and the insulation kept my water ice cold for over six hours on a hot day.

This tumbler kept my coffee hot through a four-hour morning of errands, which I honestly didn't expect. The insulation really does its job, and it hasn't leaked in my bag once.

Filled it with ice water before a hike and there was still ice rattling around six hours later. The lid seals tight enough that it hasn't leaked in my bag yet, which was my main worry with insulated tumblers.
