The Grainger professional polo shirts are designed for police, EMT, and security personnel. They are made from a polyester and cotton blend fabric with moisture-wicking properties to keep the wearer cool and dry. The shirts feature a no-curl, no-wrinkle knit collar, side vents, and either a two or three button placket. Some styles have epaulettes or badge eyelets as well. The shirts come in a variety of colors like navy, black, tan, and grey and are available in men's and women's sizes S-4XL.
