The Wenger Sahara Notebook backpack is of very high quality. The division is well thought out, the material makes a good impression. Nevertheless, I have written down the backpack on 3 star: As tall man (> 180 cm), the wear properties are on the back (time, he's made) deficient. The belts can not be adjusted so that the weight rests on the hip. A waist belt is missing. On top of the heavy weight of the backpack, which nevertheless already clearly noticeable. I have therefore sent him back, which was not a problem at Amazon. Used is now a model of Targus (Targus Campus). Half the weight, well-adjusted and 20 euros cheaper.
