14 oz. is heavier than I'd want for a waterproof raincoat, much less a wind shirt! My windshirt weighs 2.4 oz (no hood). Worn over just a light weight base layer top, it's plenty warm down to freezing while I'm hiking. In warmer weather, it's the outer layer I wear the most during stops or in camp.
