I found the vest to be of thin material and not worth the money I paid. The only thing that drew me to it was the Blackhawk name.. Its really a china made thin material vest with no extras. I would have expected a more robust vest with some inside pockets and some extra back pockets etc. no lining. Way to expensive for what you get. It will work over a fighting shirt that has thin body material and regular heavy sleeves. turns the shirt into a full shirt or jacket. Overall I would not buy this for the money you have to spend and the time it takes to arrive. The quality and robustness is just not there.
