Google Joe Rocket and call them; I did that last year when searching for the blue and white version of this jacket. Finally found a textile version for $80.00 (used, but worn only a few times). I think they said it was made for a few years and then discontinued around 2009. There are still a few new ones floating around as close-outs for $250.00 and up. Lots of fakes on ebay, though. From what the Joe Rocket person told me, yours look to be the genuine article. Keep it.
