>>1188189The padding is the classic style which is decently comfortable but over time gives way and loses most of its consistency, it will also get extremely dirty especially in warm weathers. The hip strap doesn't look like it will offer great support, then again the padding is well thick there so it might not be so bad if you tighten it well. Notice that the hip straps only seem to be linking to the rest of the rucksack in the back part, this is also not great, if the hip straps were designed so they pulled the rucksack from the sides rather than the centre, it would offer much more stability and comfort in the area.
However, most importantly and the main reason why I said it wouldn't be great for the owner's back are the main straps themselves. In the picture they are set as so they are going upwards, you have to imagine your chest in there, so you realise that the weight of the rucksack is pulling your shoulders directly downwards, creating more strain in the area. Most rucksacks nowadays have this area designed so you can pull the upper part of the rucksack closer to your body (especially comfortable for uphills) and it also helps with weight distribution. I also noticed the padding there is rather thin and the straps are probably not "preformed" so they will be uncomfortable especially under heavy loads.
As a side note, wide rucksacks are cumbersome and can unbalance you more.
I am not sure if I am explaining myself very well of if any of this makes any sense, but to me this looks uncomfortable (again, especially heavy loads, and more so in warm areas), which translates to painful if you have any back issues. Anyway I attach a picture which hopefully will help with what I said. Also I don't have that bag so I don't know how it performs and as always and with everything this is the opinion of a random dude from the internet who might be absolutely wrong
