This is the OCP Scorpion flame resistant uniform. The US Army formally issues this uniform. The top is made of a flame and insect resistant rip-stop material. Also, you can use the chest and shoulder pockets for small items. The button sleeve cuffs are an improvement over the old style. Their hook and loop cuffs require less upkeep, as well as make less noise. The top includes hook and loop fields for name tapes on the front.
