First trip for my Serac was above Green Lake in Fiordland and after 7hrs on the go I couldn't have been more happy. The only slight pressure point was the bottom of the hip belt, but I think that came more from the belt on my shorts. A small zip poket inside the top main pocket for keys and credit cards would be a bonus. Pack material feel nice and strong and looks like it could handle a good shower of rain before pulling out the rain cover. Really good access to the side pouches to grab a water bottle and all this for under 2kg. Don't over look this pack if looking to upgrade or buy your first pack.
