So strange that something can get so warm without a heat source attached. Kept my hands warm in my gloves while working around the barn, cleaning stalls, and saddling the horse and riding. Never used them before this year but I will be regular with them now. Only thing I noted was I left the pair I used this weekend in my saddlebag which was out in my horse trailer in the cold all week. At first I thought I had a defective pair because they must have taken 20 minutes before I could feel any heat generated. I think you need to keep these somewhere warm before you activate them if you want immediate warmth.
