I was also wondering about the "dynamicleather" jacket on ebay. There's also one from seller "trading.plus" which looks like the same jacket, even the same pictures, but with a darker skinned model (photoshopped?).
My other question is about the jackets from seller "dealsandstealz," which also is listed as "second skin." Looks just like the fjackets offering, but it offers synthetic and real leather options. The synthetic is almost half the cost of the fjackets coats. I'm almost willing to risk it due to the cost, but I've heard nothing about the jackets here, while the fjackets seem to be getting good reviews (though still not close to screen accurate).
