I like Columbia products. They work for and fit me well. This jacket is lightweight and totally wind and rain proof. I live in the Great Basin desert in Nevada so it doesn't rain a lot, but when it does I'm completely dry. I've stuffed this jacket in my backpack when hiking and it's been a lifesaver when unexpected weather comes along. This jacket has no lining, just a basic shell, so if you want warmth this jacket isn't for you. I wear size 10 jeans, 5'9", and 36 D and the medium is just a tad big but completely perfect with a sweatshirt underneath.
