Incredibly lightweight! This jacket provides great warmth at a very low weight, thanks to its extremely light and durable fabric and the premium 800 fill power goose down it's filled with. It's been treated with a fluorocarbon-free DWR for enhanced dirt and waterproofness. This warm, protective jacket has a stylish and comfortable fit and takes up very little space in your bag. It's so lightweight that you'll hardly notice it, while still delivering enough warmth and protection that you’ll always want it with you.
