What aluminum bottle will keep my beverage cold?

I like to drink ice cold water. What is the best aluminum bottle, that can hold at least 20 ounces, to keep my water cold for a long time?

2. You would need something insulated as aluminum is a great conductor of heat. It will conduct the cold right out of your beverage as fast as possible without something to insulate.
