Absolutley love this jacket. It is no nonsense. Obviously designed by a trail runner looking to stay a bit dry but not get over heated. It is not great for a down pour or for warmth. It is great for those long runs where the weather is unpredictable (like in the PNW almost always.) I just through in my running pack or strap around my waist. The closure on the stuff sack could be more durable, the Velcro is a little weak. It also seems to run slightly short, so if you are long waisted or wear hip huggers you might consider trying on before buying?? These are minor complaints compared to the value of this jacket. I am a solid size medium in most brands (5'8" 140lbs and the slim fit is otherwise great. I where a thin wool running shirt or tee shirt depending on how cold and I am happy as can be.
