I have just taken delivery of this pack and am very pleased:

I've not seen one in the flesh, and no reviews (just the odd product announcement), but took a gamble on it as the spec seemed too good to be true?
At first look it is perfect. I've had similar packs before and to be honest, found them to be a bit of a faff. This one is spot-on. I had designed my perfect expedition pack and was going to have one modified, but turns out Berghaus beat me to it!
Simple, uncluttered, hardly any features to speak of, and very light for it's size!
Just thought I'd mention it now in case anyone is looking for a similar pack.
