The Crye Precision Men's G4 FR Field Shirt delivers flame-resistant protection in a lightweight, highly mobile design built for operational environments. Constructed from innovative High Strength Commando Twillstop fabric made with inherently FR fibers, this shirt offers exceptional durability without added weight. Engineered stretch supports a slimmer fit while maintaining full mobility, even under body armor. Low-profile chest pockets with thermo-bonded flaps are designed to tuck in for easy access, and zippered shoulder pockets provide streamlined storage with reduced bulk. A hidden button placket maintains a clean appearance, while shaped sleeves, hook-and-loop cuff closures, and internal elbow pad pockets compatible with AirFlex Impact Elbow Pads enhance mission-ready functionality. Flame tested to ASTM F1930 standards, this field shirt is built for high-risk environments.
