In general, the whole backpack appears too unstable to be as alone one, sometimes the outer walls are extremely soft and thus not able to protect against a fall. Also I would like to see (as it already for a long time are similar in better manner!) Inside a lot more Velcro on the frame to (why not around constantly?) Look. Only in this way could then be really split the pack individually. So it is nothing but a copy as better role models. A pity ...
