In 1960, the British Dunlop Sports Company brought out its yellow Aquafort neoprene wetsuit, whose high visibility was designed to improve diver safety. However, the line was discontinued after a short while and wetsuits reverted to their black uniformity. The colorful wetsuits seen today first arrived in the 1970s when double-backed neoprene was developed. In this material the foam-rubber is sandwiched between two protective fabric outer layers, greatly increasing the tear-resistance. An external layer also meant that decorative colors, logos, and patterns could be made with panels and strips sewn into various shapes. This change from bare flat black rubber to full color took off in the 1980s with brilliant fluorescent colors common on many suits.
