I purchased this at the original retail price when it was first released (around 38,000 yen). It's made of Cordura nylon ox material and I believe it's now discontinued. I used it very little for snow mountain trekking. I kept it for many years, hoping to use it again someday, but I'm selling it because I bought a new one. I've never used it in an environment where I sweat, and the back is clean. I don't think there are any scratches or scuffs. However, the base fabric is white, so some slight dirt may be noticeable (photos 9-11). I'd like to sell it to someone who understands that it's a used backpack. [Item] Backpack 31-40L (for overnight stays in mountain huts) [Model Number] AW-AA911 [Color] White [Back Length] 51cm or more [Capacity] Approximately 40L [Notes] The rain cover can be used as a front bag and also as a map pocket. With a back panel. Includes all three accessory pouches. #andwander #Hikersdepot #山と道 (Yama to Michi - Mountain and Road)
