Next time you're parked in Houston traffic, stare at the HIWI traffic logo emblazoned on your new commuter mug. It's a good bet that you'll probably have enough time to safely look at the HIWI logo on other side as well. After that you can knit a sweater or something. Anyway, ours is steel, insulated, and has a rubber "road rage" safe grip. It holds a big 14 oz. because you really are gonna be there for awhile.
