I needed a warm coat for walking my dogs in winter and decided on the Women's Classic Heated Jacket 2.0 (4 Heating Zones) in Black & Red. It shipped from Ororo quickly even with me ordering around the holidays. I orderd on Dec 30th and it shipped Jan 3rd. It does have to be ground shipped, I believe, due to the batteries. Arrived to my state fairly quickly. Using the sizing chart, I measured as a medium for chest, but large for waist and hips. My hips measured just at the top of the large range. I decided to size up and order the XL. When the coat arrived, I made sure to leave the tags ON when it first arrived. So glad I did that! A quick try on and I realized I ordered a 2XL and not an XL. Back in the box it went and I exchanged the 2XL for an XL. This meant gound shipping for the return and ground shipping to recieve the XL. Exchanging the coat was very easy. Great customer service, easy exchange, and the XL was quickly shipping. Once the XL arrived, this is definitely the correct size. I can wear any shirt, sweater, or lighter sweatshirt with the coat. A heavy sweatshirt would probably feel too bulky and is really not needed! This coat is so well made! I am comfortably warm even without using the heating element. It would be fantastic if the heating zomes could be contorolled by zone. I'd love to be able able to turn the neck off but leave the pockets and back on or just the pockets on. Overall, I bought this coat to walk my dogs but I am wearing this every day! Love the sportness of it, love the small pop of color with the red, love the fit, and love the warmth. Highly recommend!
