I just came back from vacation, I spent also, inter alia, with this backpack. So my impression of this product is really positive. We are so wandered over hill and dale and the backpack was always always comfortable to wear by the waist belt which was well padded, the load was very well laid out. An important feature were the zippers for me the other backpacks often after the 3. 4. Using the mind to give up but here they went always without hooks or clamps on and on. The only drawback was that if you did something can look out, kept growing through the rocking back and forth the opening, but still provides the backpack normally enough space and the right storage compartments. For longer trips, however, one begins migrates easily to sweat on the back it could not change even the best breathable material.
All in all I am very satisfied with this product and would recommend it in any case !!!
