Actually I am absolutely satisfied with the jacket, it served its purpose and I like the material. Precisely for this reason I had ordered it - I wanted to have this strange running jackets that feel like they were made from some sort plastic film and somehow are also stiff. The cut of the jacket is a bit strange. The length of the sleeve fits perfectly on the belly bulges but the jacket of strange, so is air there. Bothers me not while running. However, what bothers me is that I can open only about one-third the length of the jacket when running, if I can be warm. I open them further, slipping within three steps the sleeves from the shoulders. Therefore, a star deduction. Otherwise it is as I said great!
