Many types of organizations use custom Patches with VELCRO® brand fasteners made from PVC as part of their uniform design. Uniforms in many professions must be kept up to a set standard, such as common with law enforcement, U.S Armed Forces, Coast Guard, and private security firms. The reason these patches are used in place of embroidered or iron-on patches is because of their ability to stand up to the wear and tear of harsh environments frequently encountered.
Fire departments and ambulance services will also use PVC custom Patches with VELCRO® brand fasteners as part of their uniform designs. One specific feature they often include in the design of their custom patches is glow in the dark finishing processes which are added to the lettering and logos. This finishing process helps to make the patches easy to see and recognize in lower light levels, because they illuminate and glow.
