The GORE-TEX Long Down Coat from Nanamica is the ultimate winter coat, based on the US Army M-1951 parka. The outer fabric is a waterproof, breathable, double layer polyester GORE-TEX, with a ripstop lining. The front closure has snap buttons, with a large interior pocket perfect for storing scarves and gloves. The backside of the placket and hip pocket flap have a security pocket with a fastener. Plus, the inner cuffs have a ribbing to prevent cold air from coming in. The filling is a high functioning KODENSHI down that enhances thermal properties by reflecting infrared rays emitted by the body.
