This is the Color Me Happy reflective iridescent running and athletic jacket by Free People Movement. It's made with black stretch/spandex on the sides under the arms, and a reflective material on the sleeves, back, and front that's tricky to photograph but looks amazing in person. The color looks like a cloudy silver/black most of the time, but when light hits it as seen in some of my photos, it shines a purple-green-rainbow color. The jacket really is good for running or outdoor training. The reflective parts are lined in a strong mesh material and there's a vent at the upper back, both of which help with air circulation and moisture wicking. There are thumb holes at the ends of the sleeves, and the jacket has two front zipper pockets and one pocket on the back for keys, credit card, etc. The front zip closure has two toggles, so you can zip it up all the way, or pull the bottom up if you want it partially closed but not all the way. Wore it a few times, retired it when the season changed and hoping to pass it along to a posher who will get more use out of it!
