【17-Point Heated Vest】 This heated vest features built-in heaters in 17 locations: 6 in the front and 11 in the back, providing comfortable warmth even in cold weather. It warms your body with a heating sensation, making it an ideal cold-weather item to protect you from the harsh winter, widely used for daily commutes, cycling/motorcycle riding, outdoor activities, and outdoor work. 【3-Level Temperature Control, Front and Back Independent Control】 Equipped with two power buttons, you can control the front and back heating zones separately. You can heat all 17 points simultaneously, or just the front or back. You can adjust the comfortable temperature from 3 levels: high (approx. 45°C), medium (approx. 35°C), and low (approx. 28°C), and the temperature level is easily identifiable by the button color [red (high), white (medium), blue (low)]. It's easy to use indoors and outdoors, and to adjust to the temperature and situation. 【Quick Heating, Fast Warmth, and Washable】 Adopting a Japanese-made graphene fiber heater, it starts to warm up in about 10 seconds after turning on, and the warmth spreads quickly. Filled with fluffy padding, it traps heat in combination with the heater, keeping you warm, and your body will feel toasty even when walking outside in the cold. Even if the battery runs out, you can still wear it as a regular padded vest and stay warm. When it gets dirty, remove the battery, put the USB cord in the pocket, and wash it by hand or in the washing machine. *Battery not included. 173873
