I am selling an AERIOS 18 backpack, purchased in late August 2025 at an Arc'teryx store in Umeda. It is a new, unused item with tags. I am selling this because I purchased another backpack and have not had the opportunity to use this one. The purchase history is shown in the last photo, so please take a look. Thank you for your consideration. 【Size】 Height: 49cm Width: 24cm Depth: 19cm Capacity: 18L 25aw ARC’TERYX Arc'teryx Aerios 18 Backpack Aerios 18 Backpack Black REG Black New, Unused Retail Price: ¥29,700
