This is without doubt amongst the best backpacks on the market. And I would be very surprised if it wasn`t. But, as with all things, it`s not perfect. It is claimed that the volume is 95L, but it does not feel like that when I use it on trips. I also think that the sleeping bag compartment is to small for my winter sleeping-bag. And as with all gear from Arc`teryx, its not exactly cheap. At least not where I come from.

What I appreciate with this pack is that it has a whole lot of straps you can fasten gear on. Groundsheet, ice axe, fishing rod and so on. The straps also gives you great comfort while hiking. The pack is highly adjustable, which i find very important. Although it is a little tricky to figure out at first, you will appreciate it, cause it allows the pack to fit your back perfectly. It has a large front pocket that I like , where I use to keep my jacket, camera, snack etc. There is easy access to the front, main, and top pocket with the waterproof zippers. And the pack has actually, for now, been waterproof. Although, a few drops of water will always find a way inside.

The most significant thing about this backpack is the comfort when carrying heavy loads. If you know how to load it properly, 30-40 kg does not feel as heavy as it should feel. The comfort is the best I have ever experienced.

I would recommend this backpack to hikers who is experienced with heavy loads and long trips. If you want a backpack for just a weekend on the mountain, I would get another one. Expeditions and long trips is the Bora`s main sector.

The Octane 8+ is perfect for running and biking. When I'm running in the mountains it stays close to my back and it really is comfortable to run with. You just have to, as mike.mull is saying, get the straps adjusted correctly. When i'm on my bike, whether on the mountains or the road, it works perfectly well. It is not a "big" camelback, and it's almost aerodynamically designed, which is a positive thing when you are out on your bike.
It also has a lot of storage place, I must say I'm a big fan of the expansion system. The only negative thing is that the drinking tube (not the bite valve, the tube that comes out of the hydration pack) is bouncing on the lumbar regions. I use to just turn the whole hydration pack around..

the coolest and best jacket I have ever tried. but I have a little thing to complain about, the front zipper, or the "main", zipper is not waterproof. well, at least not on mine. i've just tried it in harsh norwegian weather, and 3 places a few drops of water managed to get past the front zipper. maybe not a big thing, but when Arcteryx guarantee a waterproof jacket, and when the jacket costs 600 dollar, I expect a jacket that really is fully waterproof.
ps: i wasnt out for more than 1,5 hours..

well, except from that the jacket really is amazing, the helmet - compatible hood, the powder skirt, the design.. impressive!
