TIANEK Men Coats & Jackets,Outdoor Warm Clothing Heated For Riding Skiing Fishing Charging Via Heated Coat

I'm not a big guy but I decided to order the extra large. It definitely did come a little small. However, that's not a big deal to me because I have been getting compliments how it looks on me. So in that sense I've been happy with the product. You do need to remember that you need to have your own battery. It does not come with one. However if you use a battery just make sure it's a strong one. The jacket has four different buttons on it for each zone on your body. So that way if you want to have your arms warm but not your chest you can set that. It has three different temperatures, high medium and low. When it reaches a certain point it will drop from the high temperature to the medium. (I believe this is a safety factor so it doesn't overheat) I work in an ice skating rink and I literally use this jacket every day. It's been the best thing I've ever had. For the price it could not be beat. Even if this only lasts me 1 year, I'm more than happy to buy another one next year again.
