This is the initial Flight Pack model from Aer. I've been using it for about two seasons. There is a large fray on the right shoulder strap, and there are traces of heat treatment to prevent the fraying from spreading (see photo 6). Also, the zipper tab has broken, so I've replaced it with a substitute tab strap (see photo 7). There are also some fabric abrasions and sun fading, so please purchase only if you understand the above condition. Overall, it's still usable, but when using it as a backpack, the torn part will rub against your clothes, which may feel uncomfortable. However, it should be fine if used like a handbag.
