The new Rapid Assault Shirt is the perfect addition to 511s popular Tactical Duty Uniform. We have worked with a team of law enforcement officers and military personel across the country to develop the ultimate combat shirt for tactical use. The body fabric is a lightweight poly/cotton/spandex knit that wicks perspiration and dries quickly. Weve engineered side mesh panels to improve air flow, keeping you cool. With premium stretch the torso is form fitting without being tight or restrictive. Weve utilized flat lock seams to reduce chafing and maximize comfort for wear under body armor. The saddle shoulder construction allows for maximum range of motion for all operations. The sleeves are constructed of a tough poly/cotton ripstop with articulated, reinforced elbows. Large, dual shoulder pockets provide additional storage capacity. The Rapid Assault Shirt has a half zip entry with a woven collar that can be worn up or down. Weve considered every detail in designing the perfect addition to your Tactical Uniform..
