Bought the identical jacket in neon yellow two years ago - still have it, and it is still in perfect condition, even after hundreds of uses and washing it several times.  I saw this color on sale, and purchased it, already knowing that it was an excellent product.  It's light enough and breathes enough, that you can wear it as a rain coat in warm weather, (I wear it while running), and flexible enough that you can layer clothes and even another coat under it for cold weather.  I'm not sure why it is called "2 layer"....it is a ONE layer rain coat.  There is no separating second layer.  The hood part can fold up and be stored in the velcro-closing collar, (it is not removable, however.)  It just looks great!  I purchased the "large", which fits perfectly.  (I wear size 12-14 in most women's clothes; another comparison is that I wear a large in Columbia and Exofficio brands).
