White." Either the All-Weather Coat, Blue jacket, or Peacoat may be worn with this uniform. While once authorized for junior enlisted, it is now restricted to officers and chiefs. Members E-6 and below previously wore a short-sleeved Summer White uniform with rate insignia on the left sleeve, but the uniform was discontinued by the Navy in December 2010. Junior enlisted Navy Service Uniform The U.S. Navy underwent a comprehensive review of every uniform from 2004 through 2007, intending to replace the different working uniform for all hands and the seasonal service uniforms with a single year-round service uniform for junior enlisted personnel below chief petty officer. The Navy Service Uniform has replaced the Winter Blue Uniform and Summer White Uniform (both discussed below), which were phased out on 31 December 2010 when the rollout of the new service uniform was completed. Enlisted personnel now have a single Service Uniform. Navy Junior ROTC units also received this new uniform, where, unlike in the U.S. Navy proper, it is worn by both cadet officers and enlisted cadets. The Navy Service Uniform is a year-round service uniform to withstand day-to-day classroom and office-like environments where the service uniform is typically worn. It consists of a short-sleeve khaki shirt for males and a khaki weskit-style blouse for females, made from a wash and wear 75% polyester, 25% wool blend, with permanent military creases, black trousers for males with beltless slacks for females and optional beltless skirt, and a black unisex garrison cap. Silver anodized-metal rank insignia is worn on shirt/blouse collars and cap. The service uniform also includes a black relaxed-fit jacket with a knit stand-up collar and epaulets, on which petty officers wear large, silver anodized-metal rate insignia. Working uniforms Working uniforms are described by the navy as being worn when other uniforms may become unduly soiled or are otherwise inappropriate for the task at hand. These are worn at sea and in industrial environments ashore. In July 2010, the Navy Working Uniform and coveralls became the only authorized working uniforms. V-neck sweaters were authorized with coveralls until 2015. Navy Working Uniform The Navy Working Uniform (NWU) is a utility uniform with multiple pockets on the shirt and trousers. Three versions of the uniform exist, each with a multi-color digital camouflage print pattern similar to those introduced by other services. Type I is predominantly blue with some gray for the majority of sailors.
