Incredibly lightweight and totally gorgeous but don’t be fooled this jacket packs a punch, hard working and functional this is a working sports jacket, total wind-block in probably what is the neatest fitting jacket available. It will not spoil the enjoyment of being outdoors, you will not notice that you are wearing it. Perfect for all year round cold wind weather. This is a runners jacket it has little cross-over potential into your casual wardrobe. Supreme, we love it! A medium equates to a size 12.
