heated seat

Most heated clothing is designed for cold-weather sports and activities, such as motorcycle riding, downhill skiing, diving, winter biking, and snowmobiling, trekking and for outdoor workers such as construction workers and carpenters. Since the London Olympics, heated clothing has also been used by athletes to keep their muscles warm between the warm-up and the race.
Normal insulation works by trapping body heat, so if it gets wet from sweat or rain, or if a person stops exercising, the insulation may not keep them warm. With heated garments, a person can keep warm even if they are resting and not producing heat, or if their coat is damp from sweat.
