The fleece jacket is lightweight, comfortable and still keeps you warm even at 5 degrees. But it is not for the frost and also not totally windproof. Toll are lined inner sleeves which slide over each sub-stuff like sweater or shirt. That was a major selling point for me. Three pockets outside and a (labbrige) inside pocket take on cell phone and wallet. The jacket is suitable as an inner jacket for various JW jackets.
