"Here ends the myth “warmth equals weight."" 600 fill power down means greater insulation so we can use less of it, eliminating poof. It’s highly compactible too. Fold it into the inside pocket, pull the drawstring and voila— warmth to go. And to ensure you’re looking good coming and going, princess seams, darts and an elasticized belt provide feminine shaping. A touch of elastic inside the cuff helps seal out cold. 100% polyester shell. Machine wash. Imported."
