I'm selling this jacket because I bought it but didn't wear it much, and it no longer fits. I've listed it as size M, but there's no size tag on the jacket itself. When I (175cm, 75kg) wore it over a long-sleeved T-shirt, it was tight. I usually wear a Japanese size XL. Based on how it felt when I wore it, I judged it to be around M. Please refer to the measurements in the photos. The item is in near-new condition, but I've listed it as "no noticeable scratches or stains" just in case. However, there is some peeling on the summit mark on the left sleeve, but I think the condition is good. This is an incredibly lightweight down jacket; it's surprising. It's fluffy and quite warm. I measured it, and it weighs 306.5g. Photos 16 and 17 show some down feathers coming out. I think you can see that it uses real down. I did an image search online, and it seems to be from the Alpine Nuptse series. Details are unknown. Please refrain from price negotiations, considering shipping and sales fees.
