These thermal tops are warm and toasty, if used appropriately. They are good for sedentary activity in cold, dry weather. They should not be worn in cold, wet weather when you would be exerting yourself to the point of sweating. They do not breathe, thus increasing the chance of hypothermia in some circumstances. Remember "COTTON KILLS".
