Size W: 240mm / H: 150mm / D: 50mm Weight 220g Material Front: 66 high-density nylon multi-arm bird's eye (back: acrylic coating) Back: high-density nylon Oxford fabric (back: polyurethane coating) The "PORTER RAYS" series takes as its design concept the colors and details of life jackets worn by crew members working on American aircraft carriers. We focused on standard items suitable for daily use, updated the size and pocket specifications to make them more practical. On American aircraft carriers, life jackets and helmets in visible aircraft colors must be worn to identify the location of work departments, and each work department has its own identification color. The main fabric is durable material made of high-twist 66 nylon woven densely, with a smooth touch and enhanced abrasion resistance. It uses original multi-arm fabric to create more complex weaving patterns (bird's eye).
