NRA Range Safety Officers are a vital component of every safe, secure shooting environment. That’s why it’s essential for them to be easily seen and recognized. When you wear our high visibility, safety green RSO T-Shirt, you’ll be impossible to overlook! Built from soft, heavy-duty 6.1 oz. cotton, it’s comfortable and durable, too. Large “RANGE SAFETY OFFICER” text is printed on the shirt’s rear, with the official NRA RSO logo placed on its front left chest. Color: Safety Green.
