The "Sleeping Bag Down Jacket" is warm and comfortable, just like a sleeping bag. This year, we've reduced the volume and created a silhouette that fits just right. The color is a calm dark brown, with accents in the beige ribs and zipper. The nylon fabric on the outside has been wrinkled to give it a natural feel. The filling is a mixture of natural feathers and Asahi Kasei's Top Thermo® synthetic feathers, which have excellent moisture absorption and heat generation properties. Large zippered Pocket on both chests add a touch of work-like atmosphere.
