This is a heated vest from Mizuno's Highland Park brand. It's from Mizuno's Highland Park urban outdoor wear line, which is no longer available. I believe the product name was Thermo-Brid Vest? I've washed it by hand, but as you can see in the photos, there are small holes, damage to the logo, and damage to the power cord. I confirmed that the power turns on and it gets warm, but it might be a matter of time before it fails. There are two batteries and a charger. I regularly charged them to prevent complete discharge even in summer. Also, a NANGA zipper pull is attached to the zipper. Please understand that this is a used item and a private sale, so only those who understand this are welcome to purchase. Returns are not accepted. I think this is the most stylish heated vest. Even without using the heater, it's quite warm thanks to Thermo-Brid, so it's recommended for those who are willing to use it as is, or for those who can repair it.
