5.11 Tactical - Rapid Assault Shirt | Dark Navy
Developed in direct collaboration with military and law enforcement personnel, the 5.11 Tactical Rapid Assault Shirt in Dark Navy is a high-performance combat shirt engineered specifically for wear under body armour. The compression-fit body sits flat against the skin in a moisture-wicking 55% cotton / 37% polyester / 8% spandex blend, while the saddle-shoulder construction distributes the weight of plate carriers and chest rigs evenly across the shoulders - no bunching, no pinching, no hot spots through long operations. The Dark Navy colourway delivers a clean professional look that integrates with maritime, law enforcement, and specialised duty kits.
Durable polyester/cotton ripstop sleeves replace the stretch fabric where abrasion resistance matters - sleeves take the brunt of vehicle work, rope work, and rough terrain, so they're built for it. Articulated and reinforced elbows add prone-position durability and freedom of movement, while spacious dual shoulder pockets hold essential gear within reach without breaking armour line. Strategically placed mesh panels maximise airflow during high-intensity manoeuvres, and the seamless underarm construction with flat-lock seams throughout eliminates the chafe points that destroy comfort over a long shift. The half-zip collar adapts to conditions - zipped up to protect against sling and armour rub at the neck, zipped down for extra ventilation.
