This design is perfect for the husband who wants to let everyone know he's off the market and his wife is a bit crazy. The double-wall vacuum insulation means that your drinks will stay hot or cold for hours, and the clear lid means you can see exactly what you're sipping on. Plus, the smaller bottom means it fits perfectly in most cup holders. 

Whether you're commuting to work or headed out on a road trip, this tumbler is a must-have.
