I like mine very much. Great size, just right for me. Fits to my body as if I was born with it (after all appropriate adjustments were made). Haven't tested it on the trail, so cannot comment on it. External pocket isn't as big as those mesh pockets of Gossamer Gear G4... - I couldn't fit my 10x12 Home Depot Blue Tarp into the outside of the pack, but I hopefully don't plan to need to carry it with me much longer. Dedicated set of straps for carrying a pad... - when my new pad arrives, I'll see how well it rolls and how well those straps hold it.

First impressions - I really like it. Gossamer Gear G4 had a few things that I miss already (big mesh pockets, and straps for attaching snow showel / hiking poles), yet at the same time - one always can put those things into a side pocket, no big deal.
