if you are looking for the all-black styles, they were offered as a promo for the 2008 models and even though they are somewhat hard to find, they are still out there. you might have to get lucky and post a WTB in the for sale thread and see if anyone out there has one in their closet that they want to get rid of.
the other version is the earlier style that was black with a grey/silver stripe across the chest. those are much easier to obtain and can be found readily on ebay.
be warned, both styles run small in size so you might need to go two sizes up for it to fit right. :bigthumbsup:
hope that answers your questions.
