My 15 year old son (1.60 cm) has made a 11-day adventure tour with this backpack in the worst weather conditions. He was completely satisfied As for the strap and comfortable load distribution. 11.5 - 13 kg daily carrying weight he was very pleased, had no back or Schulterschmerzen.Der back is great padded, but despite mesh fabric on the padding you sweat probably something in the thick aufgepolsterten places, but that can hardly avoid. However, the rain cover is more for `good conscience and can maximally intercept the first droplet, but definitely you need an additional rain cover. For delicately built teenagers or women certainly a good backpack and for the price there is nothing to complain about. We have our other teens whatever ordered! our tip: take a replacement closure for the abdominal buckle, because if the backpack is on the floor, one enters as fast time on it and then it is gone ;-)
