The 5.11 Tactical Duty Uniform Ripstop Shirt is the new standard and replacement of the old style BDU. Designed with today’s law enforcement or security force in mind this shirt has all the features officers want and need. Over a year of product development went into the design of this shirt using input from police officers, special operations operators, and military personnel. The result is a new industry standard in BDU style shirts. Made of tough, polyester/cotton Ripstop, the 5.11 TDU® Ripstop Shirt stands up to the rigours of patrol and special operations. Known for superior comfort, functionality and fit, the shirt features a bi-swing shoulder for a wider range of motion.
