Our household supply of the previous version of the Cool Gear travel mugs was getting low. I was disappointed that they are no longer made, but the disappoinment vanished when the new ones arrived. They're different but even better. We always order from Cool Gear because these insulated coffee mugs are peerless. We've never found any other product nearly as good.
