[UNMARKED] Men's Performance Shirt [GRN]

EVERY FIRST RESPONDER’S GO-TO PERFORMANCE SHIRT

The design that started it all. Built by a First Responder who knew what the job demanded, the [UNMARKED] Performance Shirt set the standard for on-duty performance.

Built for those who keep it low-key, this shirt delivers strength, comfort, and dependability when it counts—on duty, off duty, or in training.

Made with our proprietary ACT1V3 Threads Performance Fabric for elite comfort, flexibility, and durability—this is the foundation of the 13 Fifty standard.

You won’t find it anywhere else. Only here at 13 Fifty Apparel.
