Female law enforcement agents all over the globe agree that the 5.11 Tactical Women's Long Sleeve A Class Twill PDU Shirt is great for in-the-field use. This is because it was designed with their input in consideration. This shirt goes perfectly with any Dress or PDU uniform due to its crisp, professional appearance. It is constructed out of 65% polyester and 35% cotton twill fabric. It already looks great as is, but it will continue to maintain its great appearance with the help of the Teflon treatment it receives that protects against permanent creases, soil stains and moisture.
