Yes! I made one three years ago - thread
here. I like it very much, and it was very easy to make, particularly as I used softshell, which doesn't need any seam neatening!
Last year I made a hood from another pattern which attaches to it with buttons, and at some point I am going to sew up the inseam pockets and replace them with patch pockets (if I have enogh fabric left) because I find the position of them a bit awkward for walking along with my hands in my pockets.
