This are the 2 Connection Leads you need to use Keis Heated Gloves with your Keis Heated Vest. I have a pair of the Keis G701S Short Cuff Heated Gloves, which do not have pockets for Batteries. These leads will connect them to my Keis Heated Vest, which is connected to my Bike Battery. If I am out on my Bike and it gets a bit Chilly, I just turn on some heat. Keis Heated Kit is great.
