This is an ARC'TERYX backpack. I used it for commuting for two years and dozens of times privately. It's very light and has plenty of pockets, and its sophisticated design, typical of Arc'teryx, made it very useful. I've used it quite a bit, but it's durable as expected, and I think it's a product that can still be used heavily outdoors. I've purchased a new backpack, so I'm using this one less, and I'd like to pass it on to someone who needs it.
