Thank you for viewing. This is a set of a Bartle Air Craft fan vest and genuine Kyocera battery & fans. I used it for one and a half seasons. One season was full use, 5 days a week, for about 2 months. After that, I used it in combination with other items, so the frequency decreased significantly. The vest has a used feel and some stains as shown in the images. There are no major damages such as tears. The battery and fans work without any problems, and the operating time hasn't changed much since I bought them, but this is my personal opinion, so please understand that it's a no-return, no-claim, no-cancellation sale.
