The Navy Working Uniform (NWU) is the multipurpose combat and working uniform of the Navy. The uniform is made of a 50% cotton and 50% nylon blend and comes in a digital camouflage oceanic colour, meant to blend with both water and ship's paint. The cap for the NWU is an eight-point patrol cap. This cover is required to display rank insignia for sailors of E-6 rank and higher. This rank insignia is sewn directly onto the cap.
Purchase the appropriate rank or rate insignia to match your personal rank or rate. You can purchase the insignia from either the local base exchange or off the Internet.
Pin the insignia centred above the bill and below the top of your NWU cap with straight pins.
Sew the insignia onto the cap with needle and thread, stitching from the inside of the cap to the back of the insignia. Remove your straight pins when you have finished sewing your insignia.
Take your uniform to a local tailor if you are short on time or unsure of your own tailoring skills. The cost will be relatively small.
