Norröna, Hadeng La, 120 liters.
Used in two years.
Frame back pack, which is extremely capacious and equipped with lots of pockets. If you don't find space for your things in this sack then you are in big trouble. When you carry very heavy weights it suites well on your back. The hip belt has a god wadding. Many smart things like opening in lower part of the sack and possibility to take the side pocket away.
Exactly the same problem as Rolls-Royce, the price. But it costs to stay at the top.
