Because this is a somewhat negative product review, let me disclaimer this by stating that I fully support and appreciate Nine Line and all that they do and have done.
I bought this jacket for the advertised "concealed carry" purpose, but unfortunately it's fairly useless for that for a couple of reasons. First, the pistol pocket is oddly designed. It's too deep, has a gap large enough for a small handgun to fall out, and it prints horribly. Unless you have a micro-pistol, there is nothing between the gun and outside of the jacket, so you can basically see the outline of a pistol rather well. The pocket is too deep and large, and the pistol just kind of falls into whatever position. Front of pocket has a velcro tab at the top and then a large gap between that and the bottom of the pocket, which allows things to fall out or grips to poke out. If you had to draw quickly, you'd be fishing for your gun for far too long.
It has no hand-warmer pockets, which is annoying and they would serve to help conceal the pistol.
It has large chest zip pockets/vents, but don't make the mistake of putting anything in there. It opens up to the entire inside of the jacket between the liner and shell, so you won't be able to get anything back out of the pocket unless you have tentacles or a long prehensile tail.
It is a pretty nice jacket and looks good, so that's why I don't totally bomb the star rating, it's just not very practical for what it's advertised as. The lack of hand warmer pockets and gaps in the inside pockets essentially gives you nowhere securely store anything unless you utilize the sleeve pockets, which are limited in size.
Also, it sags side to side extremely easily, so if you are carrying a pistol you'll have to counter-balance the entire jacket. Just my cell phone can pull one side down, which is kind of ridiculous.
