This vest is in excellent condition.  I don't see a size on it, but it looks like it is adjustable to most sizes.  I put medium to large, because as it is now it is tight on me and I wear a 52 size jacket.  But with all the adjustments, I could probably make it work.  The right shoulder has padding for a rifle or shotgun.  There are lots of compartments for just about anything you need to carry.
