Got a Padres beer koozie today. I think that's how you spell it. This thing is designed for bottles, but I don't have any at the moment. Instead, we get a can of tab for display purposes. Obviously the koozie is meant to look like a jersey. They added some piping (I believe that is the term) to emphasize that this was a jersey and not just a logo.
The opening on top obviously would work well for a bottle, but is unusable with cans. Really though, you should be drinking your beer from bottles anyways.
The back shows that this was a compadres gift. I don't think the compadres program lasted much longer than 2005. The only reason it wasn't very successful at Petco Park was that they didn't have enough kiosks. They should bring it back. I liked the compadres club.
