I've got a pair of Synergy 2 heated gloves I don't use. XXXL (3XL). These run small, I have a pair of Gerbing gloves I'm using now and they are Med and are big enough. My hand measurment is 9" and these fit just about right. About 2 years old, worn less than 10 times, in rain once, properly dried afterward. One of the cuff zip cords is missing the end that ties the ends together preventing slipping through the clamp. Cords are otherwise functional. Other than that, great condition. Both gloves heat up normally. Includes the controller. New around $180. Sell for $100 inc shipping within CONUS.
