Primary reason for buying this is not to haul it up mountains but to take stuff to work and in this regard it is perfect. The rucksack is well made and the materials feel very durable, the one exception for concern is the grab handle at the top which is rather thin, time will tell if this holds up to daily use, the straps though are fine. The main compartment is a good size and is split in two with one section slightly smaller, ideal for a laptop. There are two net pouches on either side ideal for holding a drinks bottle.
Overall very happy with this purchase.
*** Update 30/4 *** My concern with the grab handle was well founded, after a month of light use and no abuse the grab handle broke, this appears to have been a material weakness rather than fixing at the seam, a replacement is on it's way, hopefully this was a one off but knocks it down to 4 stars from 5
