This is the Aer 10th Anniversary Limited Edition Ultra Collection. It's a rare item that's not often available. I received it from my family, who took good care of it, but I'm selling it because I'm upgrading. The item has no noticeable scratches and I tried to keep it clean, but please understand that there is some minor wear and tear. The multi-functional design and detailed storage were very helpful. And I think it's very lightweight for its capacity. Also, the material is UHMWPE (ultra-high molecular weight polyethylene) fabric, which is water-resistant.
