If you have any sewing ability at all, or know someone who does, you can make your own wind shell. I have made two from 1.1 oz ripstop. One of them, a hooded, 1/2 zip pullover weighs 2.6 oz. The other is a full zip version, also hooded, with a chest pocket and two cargo pockets that weighs 4 oz. I also made a version of the full zip, pocketed one out of 1.8 oz ripstop, it weighs 6 oz and is probably a bit more robust. These were all adapted from the Green Pepper Oregon Jacket pattern. None of them cost me more than $30 to make. They are all sturdily but not elegantly sewn.

I carry a separate, store bought, hooded, WPB, 6 oz rain jacket for wet weather. When necessary, I wear the rain jacket with a set of silnylon rain-chaps and a short silnylon kilt.
