Thank you for viewing. Please be sure to read the self-introduction before purchasing, and only purchase if you understand. Workman Cooling and Heating Wear Peltier Vest Purchased in May 2025, within the warranty period. Used occasionally for gardening. There are scratches and stains, so I'm selling it at a low price. Of course, there are no problems with use. The warranty remains, so Workman will handle it. This is the latest 2025 model with five Peltier plates, allowing for both cooling and heating. It supports both summer and winter seasons, so you can use it for a long time.
