It's a jacket that fits well and is accurate to the sizing.  While the jacket has four breather holes underneath the arms on each side, it does not breathe well.  As far as rain protection goes the jacket does exactly what it's supposed to do, it keeps the rain out. However I'm sweating so heavily inside this thing that I might as well not be wearing it.
 When I take it off my shirt is completely soaked.  I'm wearing this in weather that's anywhere from 25 degrees Fahrenheit to 40 degrees Fahrenheit.  I can't imagine wearing this thing in warmer weather without turning into a swampy mess. The jacket's very attractive and it looks great it just performs poorly in terms of its breathability.
