These high density embroidered sergeant chevrons are the standard for law enforcement and security uniforms. These sergeant stripes will last a long time and are designed to not fade even after much time on duty in the sun and many machine wash/dry clean cycles. These chevrons are typically worn on the arm of the uniform. These are sew-on embroidered rank patches and can easily be applied to the uniform. If desired, you can sew hook backing to the back of the patches. CopQuest has been serving law enforcement for over two decades and is proud to be an American small business. These can make great gifts for police officers, sheriff deputies, security officers and other law enforcement that recently promoted to the rank of sergeant. Note: If department regulations require a 3" wide royal blue/white stripes on black felt backing, these are the only chevrons you will need as a sergeant. 3" wide chevrons are one of the standard sizes for most law enforcement uniforms. The other popular size is 3.5" chevrons.
