Brand new. For someone 179cm tall and weighing 70kg. Body type is slightly thin around the waist, but with broad shoulders and muscular shoulders. This is a military down jacket, so it's designed to be worn with inner layers. Therefore, it might have more room than usual. It would probably be a perfect fit for someone 175cm tall with a standard build. With a boa inner shirt and a thick flannel shirt, it's a perfect fit for me at 179cm, with the hem 3cm below my hip bones. It's a UK size, but consider it to be about a Japanese M. I think it would fit someone in the 160cm range, and even someone in the late 170s if they're not overly muscular. The forearms are also designed to fit snugly with the padding. It's impressive how warm it is despite being lightweight. Made of Paratex material. The sleeves are slightly long with thumb holes, so even if you have long arms, you don't have to worry about them being too short. It has a technical fit, with the cutting and sewing designed for a snug fit. In Tokyo, you could probably get away with just a T-shirt underneath even in mid-winter. Bikers might want to wear a slightly thicker inner layer, but because of the fit, it's excellent at windproofing and heat retention.
