coffee holders
I looked on their web site and I don't see the one that I have, but I'm sure you could find something similar. My lid screws on and has a rubber o-ring and seals air tight. I've driven to work before with the cup full of hot coffee and it was laying on its side and didn't drip a drop.
Bottom line is the cup holders in the car suck, and you need to get a cup to deal with crappy holders.
