Thank you for viewing! I purchased this in 2023 and used it twice, but I'm selling it because I no longer use it. The main feature is its lightness; it's very light and also has a good capacity, making it very easy to use for one-night trips. As shown in the explanation in the 18th photo, the side pockets can be used in various ways by changing where you hang your belongings. The mesh pockets on the shoulders, waist, and sides have fine mesh and stretch well, so you can put large items in them, and the strength is also excellent. The mesh on the back is also cool and comfortable. The waist belt and shoulder straps are adjustable, and I personally like that you can carry it on your waist when your shoulders get tired! As you can see in the 3rd photo, there are about 3 scratches on the front and sides, but they are not very noticeable. I would like to avoid any troubles such as returns. Thank you for your understanding. Arc'teryx products are often a bit pricey, but I'm selling this in good condition and cheaper than new, so if you're interested, please consider purchasing it and enjoying the outdoors. I can consider price negotiations, but it might only be a small amount. Feel free to comment. I hope we can have a pleasant transaction. Thank you. - Brand: ARC'TERYX - Model Name: AERIOS 30 - Color: Gray/Yellow - Features: Stretch mesh pockets, adjustable straps From the official HP: The "Aerios" series is a backpack series specialized for hiking and trekking. The biggest feature is that it is an ultra-lightweight pack with a 30L size and 900g, yet it has the strength and durability to handle overnight hiking, that is, staying at a mountain hut for one night or more, or even lightweight tent camping. Therefore, it can be used for a wide range of activities, from fast & light speed hikes to day hikes, summer mountain trekking, and even mountain running.
