This is the 2025 model of Workman's Peltier vest. I've used it two or three times, but since I don't use it very often, I'm putting it up for sale. Cooling is a focus right now, but it can also provide warmth, so it can be used in winter as well. Regarding the Peltier cooling surface, I've wiped it down after use, but there are fine scratches and what looks like clouding. It's difficult to see because of the mirror finish, but please understand. Also, please note that the battery has some signs of use. Regarding shipping, the Peltier will be shipped attached to the vest (as shown in the last photo). The items included are what's shown in the last photo + the instruction manual + the outer box, so please check. Thank you. Instant cooling to -28°C, instant heating to +39°C. - Model: ICE×HEATER Cooling and Heating Clothing - Size: Free Size - Cooling Temperature: Instant cooling -28°C - Heating Temperature: Instant heating +39°C - Battery: With battery Thank you for viewing.
