Does not have advertised features!
Obviously, the main feature of this pack is the integrated AvaLung but the features that pushed me across the line to buy the pack were the advertised diagonal ski carry, helmet holder, and fleece goggle pocket. All websites I viewed, including BD's, claim it has these features. Even the instructions included with the pack makes this claim. It does NOT have any of these!! I contacted BD directly to ask if I was overlooking something and they said I was not, this new model does not have the diagonal ski carry, helmet holder, or fleece pocket, and they had not updated their literature from the previous model. Then, the guy goes on in an attempt to get me to sign up for the BD newsletter to learn about new products. Ha! The BD rep asked me what we could do to resolve the issue but I have not heard a response to my suggestion. I just returned from Gulmarg and, fortunately, did not have to use the AvaLung but missed the other features. The Dakine Guide pack is superior, way superior, to this pack but, of course, does not have an integrated AvaLung.
If this pack did not have the AvaLung, I would consider it a very poorly designed pack that no person looking to do multi-day ski touring would think for a second to purchase.
