This is a vintage jacket from the 60s. It was originally re-purposed and redesigned to wear to burning man so that the lights would show up in the dark. But unfortunately never got to go the year it was designed! It has a little bit of yellowing on it, but that doesn’t hurt the look because it can be wonderful for cosplay, festivals or on the playa during burning man nights when you are out with one of your best costumes underneath! Yet it will keep you warm ,as a desert gets a little cold at night during these festivals. But use your imagination and you can wear almost anywhere . It makes good party ware ! Also to a party of any special occasion. This is a rare find from the 60s and repurposed and redesigned so you will not find another one like it. This is one of a kind . This is also a final sale. It is a size small to medium . The lights have two small on and off buttons on an inside hidden pocket. The lights have three speeds. The battery’s are replaceable but the battery’s can last a year at a time.
