The CK technicians backpack plus, sits well on the back and can be worn properly both without, as well as with jacket.
I especially like this, the semi-circular shaped shell stand and the wide, padded carrier straps. These are mounted at a safe distance in the neck, so they do not constrict there when carrying or constrict the skin in the neck.
The narrow shape of the backpack, also leaves the poor the necessary freedom of movement, such as when climbing up a ladder or steep and narrow stairs.
The material of the backpack has proven to be robust. The seams are sewn stable and the handle also makes a strong impression, even on the few days previously tested permanent addition.
The zippers are with me an ordinary load and continue to be smooth, the zipper is easy to grip.
The bottom tray made of plastic has proved itself for me. Since the backpack came to stand even in the low water. In any case, spraying and rainwater can confirm impermeability. More, he has not yet gotten.
The stability is good if you take care of the distribution of the heavier stuff. Here are particularly the extra belts positively noted that prevent the open backpack will not rise too far and thereby possibly also a tendency to tip. In addition, they seem to really endure something.
Also very positive, I feel the many pockets inside, offer the loops and Slots for all kinds mold. They are also deep enough to hold all kinds of work material in place. Here, then, the peaks of about screwdrivers, well protected sunk in pockets.
A patch on the backpack Dokumententasche serve me for free stuff, but here look for documents and instruments, and / or a tablet space.
Besides an additional pocket for mobile phones and a professional name, I do not need another place outside on the rucksack (the rucksack plus CK technicians but also do not offer). Too many pockets but would also be counterproductive because the backpack is supposed to remain locked.
So much for the positive points; the negative, however, are dealt with quickly:
Backpacking missing reflectors, these are eg required in my company, so I had to improvise here.
And it lacks a chest strap. Due to the weight during the transport of the tool, would be such a real advantage.
For me, this backpack has absolutely proven, at this size it is perfect for use in the workplace and carries all before it; I default, need a layer artisans.
