My second osprey aura AGI love the backpack! It has so many pockets to organise your pack out there in the wild and it's so easy to carry, even when you're going with a heavy weight over 10kg. The hipbelts are suiting me very well and they have small pockets which is also super nice to keep some small stuff (mobile phone, etc) when it rains, you can put the rain cover on to make it waterproof. I have been hiking in the swedish fjäll, where it's really moist and raining quite much. After a full day of rain ( with having the rain cover on) my stuff inside got a little bit wet. This happens with every backpack that isn't made from a waterproof fabric, but you have to know that when it's heavy rain the whole day, you need drypacks inside to keep your stuff dry. This is not meant as criticism, more like a piece of advice for those, who are planning to hike in very moist areas (who actually likes that?!)
Apart from that, the pack starts to "squeek" after a while. I sent my first Aura AG back to osprey because I was annoyed by that squeeking sound and they sent me a completely new one after a few days. So the service is super fast!! But I have to say, my second packs has a light squeeking as well...
To conclude: I love my pack! I love the design, I love the size, I love the antigravity system. That's what counts for me. You can get this backpack for a very good price and that's the point. If you want something better than this, you HAVE to spend more money. The price is absolutely fine for what you get. I'm planning to get something with a waterproof fabric next, but that's going to be a little bit "extra".
This pack has been on many trips with me, in the woods or in the city, and I can just recommend it! :)
