This is possibly the warmest jacket I have ever owned. Unfortunately, I bought the wrong size, and realized it too late. I have worn it twice outside on cold, bluebird days. Anyways, it's 800 fill down, has a Winstopper 30-denier Ballistic nylon shell, a removable hood, a chest pocket, and fuzzy pockets when your hands get über cold. It's super light (less than 23.6 oz), and can compress really small. This palace of warmth can be yours for $280. I'll ship anywhere.
