Leak-Proof Travel Mugs???

[CoffeeCzar]

I have been looking for a travel mug to take with me to school that is leak-proof so I can put it in my bookbag or leave on my desk without worring about the person in front of me spilling it when they lean back and strech. :evil: I was wondering if you have found any good mugs/tumblers that are leak-proof and not to small. I would like to be able to find one about 20 - 24 OZ.

I heard that the Nissan 14Oz is good but it seems to small. Any suggestions??

Why not a thermos?
