They are perfect custom patches crafted out of vulcanized PVC rubber which is flexible and elastic. As PVC rubber is so durable, dyed in various colors, they are popular on logos, icons, uniforms, outdoor gear, and even footwear. Traditional motifs in ethnic fashion mark their emergence throughout the ages. The main characteristic that sets them apart are their ability to withstand abrasions, chemicals like those referenced in ASTM D2000, and the detail and color used to create them. Culturally, these patches are versatile, serving as tactical morale patches in the military, brand logos for streetwear, and reigons utilize different colors for symbolism such as red for luck in China and green to symbolize nature in the Middle East.
