This is likely a limited edition red jumpsuit with the YAMAHA technical center logo, only available to those who attended Yamaha's technical center. It was purchased new and stored in a drawer, appearing to be in near-new condition. This item is from the 70s-80s and is no longer sold, making it very rare. It's also in remarkably good condition for its age. Other similar items are listed, but while many feature the SUNDISK logo, this one is branded SUN ASAHI with a gold embroidered logo, making it quite luxurious.
