The 5.11 Tactical Multicam TDU Rapid Assault Combat Shirt features a specialized Multicam colored pattern that reduces visibility in both visual and IR light spectrums. This combat shirt was engineered with direct feedback from military and law enforcement professionals as an ideal base layer for tactical use. The body section is made from a poly/cotton spandex knit blend to provide an agile and flexible base with moisture wicking and quick drying properties. The sleeves are made from an ultra-durable poly/cotton rip-stop fabric that can stand up to the harshest environments. The saddle shoulder design will take the weight of your plate carrier and body armor without pinching or bunching up. Large shoulder pockets provide quick, convenient storage and the mesh side panels offer enhanced breathability. This shirt's integrated woven collar can be worn up or down to suit your current needs.
