Jouset

The double-wall vacuum insulation genuinely works — my coffee stayed hot through a whole afternoon of errands, which never happens with other mugs I've owned. The 14oz size is perfect for my desk, and the lid fits snugly enough that I don't worry about spills when I toss it in my bag.

I’ve been using this tumbler on my commute and it’s already become my favorite desk companion—the double-wall vacuum insulation keeps my iced tea cold for hours, even in a warm car. The 14oz size is perfect for a solid serving without taking up too much cupholder space.

My coffee stays hot through my whole morning commute and then some, which is exactly what I needed. The 14oz size fits perfectly in my car's cup holder and on my desk without taking over. I've already ordered a second one for my husband.
