My requirements for a backpack I would therefore be regarded as high.
Space and stowage:
The (rear) main compartment of Wenger Carbon (comparison) swallows not only a 15.4 "laptop with no problems and Wimpernzucken, it wraps it also makes sense gepolstertund without these touches down on the backpack floor, it fits beside it easily even a full A4 Leitz Whether every 17 folder additionally into it. "laptop fits (?) I can not judge because my own 13.3" is significantly smaller. Think, however, that this is a question that can be answered only in practice in individual cases. A ground-level power part specialist managed in this area to make sense cable, mouse, other peripherals and / or the AC adapter.
The front main compartment also absorbs well 6cm A4 books, brochures or blocks, and here create network-part pockets ordering divisions. Alternatively, an average laptop can be parked easily with protective sleeve here. Or just a tome with 600+ pages. I stress "in addition to all that in the back of specialist outsourced".
The front organizer provides sufficient space for writing materials, external hard drives, carabiner for Schlüsselbünder and storage space for any paperbacks as "Bahnlektuere". A 3.5 "external hard drive can be here as well stowed.
In the head region there is still another subject, which receives an MP3 player (with a "cable lock" to the outside world) or as a storage space for peripherals can be used.
Two exterior mesh pockets offer space for smaller bottles, but are neither opaque nor particularly large. I use them rarely.
Ergonomics
The belts are of sufficient size and well padded, with corpses "cushioning" by elastic members, and the sheathed handle (inside a steel cable) haptic cuddly. The straps are adjusted by adjusting straps provided with Griffstuecken easy .... luxury at one wants to get used.
However, the "Handytasche" on the belt is for smartphones (here a Galaxy S +) is too small, an MP3 player finds there but good place. Also this ... luxury.
Prolonged wearing, at a loading of 10 kg is also run after an hour and climbing stairs no-felt problem. In some Situationn a chest strap would be nice, but regularly only additional Wirniss.
Durh a stiffened bottom is the backpack in unilaterally laden stable and vertically, even in a moving bus / train.
Hard facts:
The outer skin made of double fabric looks more stable, has good wipe (tested on a klebirgen chocolate shake) and largely water-resistant. The zippers are unusual for backpacks smoothly well sewn and sealed in Zwiefel with a suitcase lock - a real bonus in crowded ÖNV. They are also sufficiently water-repellent, but of course not "tight". Only those who go diving with his backpack yet?
As office backpack for people with space first choice. Unobtrusive, high quality and reasonable designed. Sufficiently low.
Honestly, what more could you ask more seriously?
Buy recommendation!
