I absolutely love this running jacket!  I bought it in white and I love it because it makes you more visible in darker conditions.  It is really lightweight, so it is comfortable to wear in the 50's and below.  It really protects from the wind well.  The zipper does not rub my chin.  The pockets are easy to access when running.  And my absolute favorite aspect is that the sleeves come off to convert it into a vest so that you can wear it when it's a little warmer and you don't need arm protection from wind or rain, etc.  I look forward to cool days now because I get to wear this jacket.  I hate leaving home without it!
