First, I have to say it is refreshing to get a jacket that fits a fairly average guy very well.  It is not to tight in the arms and chest and not too baggy around the middle.  It has enough room for a long sleeve shirt underneath without feeling cramped.  Second, the jacket is so light and comfortable you wouldn't expect it to provide much warmth, but it does.  Third, it is made of recycled products to reduce environmental impact.  Fourth it is well made with heavy duty twin front zippers, pockets zippered with water resistant zippers, and good attention to detail in the stitching.  The side pockets at big enough for gloves and the top pocket is wallet sized.  Throw in that is iv very packable into it's own pocket and the jacket is a real winner.

I would mention that I am rating the warmth in a California January.  Not in cold country.
