This is the Arc'teryx Cierzo 18. It's a popular packable backpack from Arc'teryx. Designed for rock climbers and ice climbers, it's ultra-lightweight and compact, allowing for unrestricted movement and ease of use in harsh environments. Of course, its pop colors also make it eye-catching for everyday use in town. The inside has some stickiness and deterioration. The outside has some dirt and scratches. Please judge the condition from the images. Although there is some wear and tear, I think you can still use it for a long time. ■Size■ Capacity: 18L Weight: 265g ARC`TERYX Arc'teryx cierzo18 Cierzo 18 Orange Attack Pack Packable Backpack Rucksack Please understand that this is a used item before purchasing.
