i was very excited to see this product go up for sale, so I ordered one for myself and one for a friend. I think its a really cool idea. Unfortunately it seems very cheap, and I doubt that it's thin single layer of wool will ever keep a can of beer cold. I was envisioning something along the lines of two pieces of fabric with some insulation in between, not unlike the hat that made it famous. When you figure in the shipping it makes for an expensive novelty.
