The color looks close, and it's certainly a nice duster. It's not exactly Deckard's coat though. Check out the one at Abbyshot - it's fairly accurate. You'll see the difference.
You know, this is EXACTLY what I like about this board. Out of the blue someone mentions ABBYSHOT, a website I've never heard of. Anyone here buy an Abbyshot Deckard jacket? OR... any Deckard jacket at all?
Get rid of the shoulder cover (and reattach it as a back flap), switch the snaps to tortoise shell buttons, and add an inside quilted piece to the collar, and it would be pretty close. The waterproofing already gives it that rained on look.
