This thing is more like a rain jacket, as it is 2/3 plastic.  The faux-military label says "Coat Hot Weather" ! I want 100% or at least 60% cotton in a BDU suit.
It doesn't list the fabric content, but it is is the Amazon description, which I should have considered before purchasing.
Also, I weigh 235# and am 5'10'' and a XX-Large barely buttons in front.
It is pretty stiff and the laundry directions on the label make it sound pretty delicate.
I plan on washing it a couple times and then wearing it over a hoodie in the rain , if it doesn't shrink.
