Purchased from the official website in 2025FW, with purchase history attached in the third image. This size is only available on the official website and is sold out. Brand new, unused. This is the revised Atom SV. It's the warmest in the Atom series history. I wanted to own it, and compared to the Atom AR and heavyweight versions, I actually felt it was the warmest. The even distribution of Coreloft in the arms and hood, along with the increased wind resistance of the material compared to previous models, is thought to have increased the insulation. The size feels the same as XXL. The even distribution of Coreloft and the durable material result in a more masculine silhouette when worn, with a well-defined hood and a stylish look when the zipper is open. I think it's the perfect specification for everyday use in Tokyo. Size guide. Please use as a reference as it's measured by an amateur. Shoulder width 60cm, body width 70cm, length 80cm. Thank you.
