This is the Arc'Teryx LEAF Recce Shirt AR. 

They do not sell these anymore and are nearly impossible to find. Bought this thing about a year ago when everyone started selling there's in response to Arc'Teryx prohibiting the ability to buy from sellers. 

Really saddened to part with this as I'm very unlikely to find one again in this condition.

Never used apart from flexing in the mirror. All my friends said I looked really CAG and OPERATOR in them.
