The Crye Precision Men's G4 Hot Weather Combat Shirt is engineered for maximum breathability and lightweight performance in arid environments. Designed to be worn under body armor, this combat shirt features ultra-lightweight, fast-drying nylon ripstop sleeves with moisture-wicking and UV protection, while the torso is constructed from Polartec Power Dry mesh jersey with antimicrobial fiber to keep you cool and dry. Reinforced high-wear areas enhance durability without adding bulk, and flatlocked seams increase comfort during extended operations. A minimal zip collar allows easy donning and ventilation, shaped sleeves enhance mobility, and the extended back hem helps keep the shirt tucked in during movement.
