I was shipped the wrong color but at least tried it on in some 40F degree weather to test the warmth out and felt almost no warmth at all. It was my first time trying a lightweight down jacket on, but I was expecting a lot more "wow" factor for ~$300. Not only was any additional warmth not noticeable, but the sleeve cuffs were definitely over-sized (not good for insulation) and the material looked and felt kind of cheap. Doesn't mean it IS cheap, but for the price this jacket cost, I would have been disappointed if I had decided to keep the jacket in the right size. I, however, decided to get an Evertherm Jacket from Eddie Bauer instead, and for basically the same price I'm far more impressed with that jacket after 2 months of use.
