The finished garment is padded through direct injection with the finest feathers, specifically treated to resist garment dyeing. Garment dyed with the addition of a special PFC-free anti-drop agent. RDS - Responsible Down Standard certified. STYLE Hood, with horizontal drawstring, edged in stretch nylon tape. Valet-stand hand pockets, with zipper closure exposed at the bottom to serve as a zipper pull. Stone Island badge on the left sleeve. Shoulder and side seams edged in nylon tape. Cuffs and bottom band edged in stretch nylon tape. Two-way zipper closure.
