Take a look at this one - The Beer Pouch Sweatshirt. A 30 square inch pouch with an elastic band and an insulating band to keep the beer cold also has a hood. It can also hold other things like a bottled water, coke in can etc. and to make it easier, you can also put straws in it so that you don't even have to bother taking it in and out to drink, instead just sip from the straw.
