Shipping fast. Shipping from China to pottamat in two weeks. I ordered a vest with nine heating plates. Sent a vest with four plates ((after opening the dispute in silence returned some of the funds for the purchase. The vest itself is of good quality. Sidewalls stretch. Size 3XL tightly sat on the Russian 50-52. I think at 48-50, too, will be right. For height 185, the length of the vest is normal. Heats!!! Quality is satisfied, thank you to the seller. If vest turn off, then my Power Bank goes to sleep and in the future the button on the vest does not wake it. It is solved only by pressing the button on the battery, which is somewhat uncomfortable. On the vest are 2 outer pockets, and one inner with a wire for the battery. Inside the lining of aluminum material as on Columbia jackets, the same quality. At-15 on the street set turtleneck, vest on minimal heating and ski jacket (membrane)-In a quiet walk, the feeling is interesting-the hands freeze, the body is hot. Perhaps a jacket (with sleeves) such a product will be more interesting. But his function performs.
