I know that this is an old game and might not get that much attention from the staff anymore.
I still wanted to mention that, when you have the Windblocker jacket equipped and aiming down the sight with certain primaries, you can see a part of your jackets shoulder floating on either your left or right depending on where your over the shoulder cam is looking.
You can see it more if you aim up and less if you aim down.
Screenshot below. That brown beech smudge on the left is the part of the jacket.
