Just got this jacket in the mail today. My first impressions were quite good. I am 5'10 and weigh 160, with a 41" in chest. I ordered a size small and it fits me well. Not too loose, not too tight. The jacket is light weight, and is actually a little darker in color than it looks in the photo. It is more of a true "olive drab" color than "olive green." After I have put some real wear and tear on this jacket I'll write a follow-up review to see how durable it is over time. As for now, I am quite happy with it.
