This is an Atom AR Hoodie purchased online from the official store. The size is men's M, which is equivalent to a Japanese size L. It's the same as the current Atom Hoodie SV and last year's Atom Heavyweight Hoodie. The SV has a stiff fabric that feels crisp when worn, but the AR is soft and supple, making it comfortable to wear. It uses synthetic insulation, so it can be washed in your home washing machine. I had it cleaned for this listing. There are no noticeable stains or scratches, but it is a used item, so I would appreciate it if those who understand this would be interested. Regarding shipping, I usually ship within 1-2 days, but I often travel for work and am away from home for extended periods. In some cases, I may not be able to ship for a week to 10 days. If you need it urgently, please check with me in advance via comments. ARC'TERYX / Model: ATOM HOODIE Color: Red
