It's possible that those jerseys were made for Pat's and you'll never find another one like it.

If you're just looking printed jerseys, maybe try http://www.love2pedal.com/ - I've never ordered from there so no idea on quality, but they do have many printed/graphic jerseys.

If you're looking for a place to make you your own jersey, those exist online as well but I don't have any of the sites handy nor can I recommend anything really.
