Having the right Muscle  shirt for a ballistic vest is crucial for comfort and performance. Specifically designed for officers who want a compression garment, the 5.11 Muscle  Shirt fits that need with its unique design and features. It is constructed with our moisture-wicking, anti-microbial and quick-drying fabric and features three distinct zones of compression. These compression zones provide officers with added strength and protection in the chest, abdomen and back. The saddle-shoulder construction offers greater range of motion and an underarm mesh panel allows moisture to vent and evaporate easily. The Muscle  shirt has flat-lock seams to reduce friction and prevent chafing. The 5.11 Muscle Shirt is designed to wear under body armor but is also great for casual and workout wear. Made of 88% Tactel® nylon, 7% nylon and 5% spandex, the Muscle  Shirt is designed to last. 5.11 Tactical Series is proud to provide you with quality, durability, innovation and value in our Muscle  Shirt.
