This is a Mountain Hardwear thermal garment using Octa. I purchased it last winter and wore it twice before storing it in a dark place. I believe it's in good condition with no noticeable scratches or stains, but please check the photos as it's been stored by a private individual. 〈Quoted from the official website below〉 Features 【International Size】 This is a lightweight, compact long-sleeve shirt that can be used as a layering piece throughout the year.
