Resume: Recommended and I would buy it again!
Pro:
+ Sitting well, distributes the load perfectly and presses nowhere
+ Relatively easy with nachgewogenen 1550g (less as indicated)
+ Thought out with lots of useful features (ice ax and sticks attachment, rope fastening tape, ski loops, card pocket on the outside, etc ...)
+ Robust and good workmanship
+ Large lid compartment
Contraindications (nothing worth mentioning):
o / - handle disappears behind the lid pocket
o / - crampon bag for crampons ungeigent since weight are very far outside and train backwards, but it can also perfectly used for a helmet
- Zipper on the outside does not necessarily have, clutter rather consider when moving around, that this sometime breaks and the backpack with the zipper is more prone to water ingress
