ISO G-Star Raw Crusader Overshirt jacket

I'm searching for this jacket sometimes called an overshirt. The jacket looks green but sometimes it looks khaki. I'll take either one. I've heard this item runs small, so I'm looking for a L or XL. New or used, it doesn't matter. Please let me know if you see one available or if you've got one to sell. Please know that just because I'm looking for this item, I'm shopping on a budget. Thanks and happy poshing everyone!
