This is Komine's Electric Inner Hybrid Vest. The size is L. The temperature can be adjusted in three stages via switch operation. I have stored it in a dark room without using it even once after purchase. Operation has been confirmed. There is no charger. Everything in the photos is included. Since it has been stored in a dark room for a long time, I have listed it as "Like New". Although it has not been used, it has been in someone's possession, so please refrain from purchasing if you are concerned.
