Lots of other cool "team" jerseys available from this cat. I'm enjoying mine so much I may have to order a Planet Express jersey, or maybe wear the colours of the Stark Direwolves.
The only downside is that the jerseys tend to be ordered in batches, so if you've missed-out on the order deadline for your favourite, you might be waiting a while before it's available again. Still, with so many cool designs, there's bound to be something to help you fly your geek flag at the rink.
