Accustomed to wearing hiking bags very good, I was really disappointed by the rigidity of the seat back that is tossed regardless how one adjusts the straps. I thought that the additional strap allow good support but that is not the case and the setting is laborious. Finally, despite the use of technical terms for the folder, the contact is unpleasant.
After three hours of walking, I was in pain almost everywhere and I ended up taking the device around the neck and the shoulder strap wedge in, pressed against me to distribute the weight. In defense of the bag, my reflex is not really a featherweight and my back is pretty fragile.
Listed ergonomics, very good things. The location for the foot dragging is very is forgotten when the foot rest at home. For quick start the unit, simply snap the smaller strap and slide the bag which is then presented with top opening. it works well and the bag despite its small size makes it well rig a DSLR with mounted 250 mm without problems. It remains what store a second lens and a flash, plus small equipment in the isolated compartment.
By cons, he faults its benefits. There is a higher bid pockets, compartments, slots, it would make almost afraid (to put pen and spend 10 minutes searching the then).
Very good point, rain protection is perfectly adapted very fast to implement and intelligently row (subject to recall four compartments in which it is stored).
Finally, all inspired great confidence side strength. The quality is there, the seams inspire respect (the box-type logic, not luxurious but indestructible).
12/20 so with a value Honourable price.
