This jacket is stylish, comfortable and incredibly functional!  I took this with me backpacking in ireland for a month and it proved to be a 100% essential item.  It takes up almost no room and I used it almost everyday (yes...it actually rains that much in ireland...but it is a great trade off because it makes everything green and beautiful).  It's very comfortable and completely waterproof...don't count on it to offer any warmth and you won't be disappointed!  I got poured on during a hike and with the jacket zipped and the hood up I stayed warm and dry.  I usually wear a size small and it fit well...perhaps a bit big actually if you aren't going to be wearing a lot of layers under it I'd almost suggest to size down.  I was usually wearing a few layers along with a chunky sweater and the jacket was still quite roomy.  The price on this also can't be beat.  I will take this jacket with me on every trip I take from now on I'm sure.
