On average, I have 10kg promoted it, at the end of my three-week tour of India there were then 15kg. It's my first trekking rucksack and I'm very happy with it. The two integrated bars ensure an even weight balance, allowing the prolonged wearing.
The only drawback: after my return and after emptying the backpack I realized that the partition wall has a hole because the seam is risen. I really have promoted many textiles and a stone statue at the top of which will probably have made a contribution to it. Likewise, I have often crammed my hand luggage up.
Still, I would have liked a stronger seam. A thicker thread would bring the manufacturers hardly about winning.
On the whole, I am very satisfied and would buy the backpack well again.
