I am writing this review only to push the evaluation of the backpack to the top - I think he's absolutely great and have no complaints - and I'm really a critical person ... Keep the straps, the zippers go well, really enough space in the interior far beyond notebook and accessories out - exactly what I wanted. To wear it is super comfortable. The backpack itself is very easy and the weight of the luggage is distributed so good that you hardly feel it. For durability, I can not say anything because he still is very new - but the impression is great and 25 years warranty speak for themselves ... Only the front to be closed chest strap dangles equally around the area if you do not need it - is indeed adjustable in height, but not entirely removed - but quite honestly, so I can really live well, therefore 5 Stars!
