I am 158cm, 5,2" and weigh 52kg, 115lbs, I bought the size S jacket after using the fitting guide. After the purchase I went to a store and tried on the Teta shell jacket and the S size there was much too big for me and the XS would have been better. I could probably go down one size, but I rather have that extra air to keep me extra warm. The fitting is not very streamlined, but I really don't care about that when wearing this kind of gear. The hood fits perfect and keeps wind out with no problem, so it definitly puts and end to the cold air on the back problem. There are two big net pockets on the inside, keeps lots of things and with the size S I could fit a bigger compact camera in there without problem. I were mine both for outdoorskiing and walking and just when the weather is crappy. This is my first Goretex proshell jacket and I must say, it was worth all the money. I bought the black one, because I don't want to wash it at all if I can manage, since it will not wear down on the quality, if it smells I just put it outside for a night. I used the chat function when I bought it, because I wanted a jacket that covered my waist line and wanted it also to cover my hips and part of my bum. They said that it would , but I feel more that it ends past just or a little bit below the hip. It is really lightweight, easy to move in. I love it and this loveaffair will last a life time. I took one star away, because I just find it annoying that you pay pretty much for a premium jacket and when you look at the label it says "Made in China", it is just irritating.
