I've been looking around and have not had any luck. I've been searching around for the pattern, but the name doesnt pop up and I haven't seen a color like that at all.
Then I tried looking for the same design at places like PacSun or a surf shop. Maybe even a jacket for the Snow or Skiing. I've seen jackets that partially resembled what was seen, but finding everything that matched it is impossible, especially the pattern.
From what I've seen, here's what to look for:
The cuffs and the bottom of the jacket are black
The string that closes that hood part of the jacket is a drawstring, that one can stretch.
The outline of the pockets are lined with black.
The hood has a black outline around the edges were it was sewn.
The inside of the jacket (well the hoody part at least) is black.
The material, it look similar to what I've seen at Sporting places, not quite felt, but something that is waterproof.
If you look at a screenshot when he's taken out the sniper, his right arm sleeve has a pocket.
If someone can track down a name of the pattern, it would help narrow the search.
I searched for Addicts clothing or even Carhott, since they were ones that used unusal patterns (Such as Blue, Silver, pink). But the jackets didnt have the right details. So the search continues.
