Taion Crew Neck Pullover Down An insulated pullover from Japanese outerwear company Taion, made from a high-density nylon shell which is water-repellent, and lined with a smooth and comfortable polyester taffeta. It has a 650-fill-power insulation of 90/10% mature waterfown down and feather for proper winter layering. The jacket has a sweatshirt silhouette with a ribbed crew neck, elasticated cuffs and hem and a snap-up chest pocket, along with subtle zippered handwarmer pockets. This is a regular fit - I'd recommend your usual size to go over a tee.
