Looks like it'd be a perfect summer Alpine pack.
As for your comment about light weight packs, you've obviously never noticed the Arc'teryx Cierzo 35 which is about 600gm.

I'm kinda torn between the two, but I think that the Montane despite the extra 300gms will probably be a slightly better pack in terms of comfort and features. Especially the small pouch on the hipbelt, I really like them, very useful.
