Shortly thereafter, I found this bag for 13. I have now satisfied a few weeks in use and am. The bag is very well padded and has 3 storage spaces. The largest storage space is intended for the device itself. Here my Surface fits in 2 incl. Type Cover. The bag is but "designed so that even still fit in larger devices. Thus I have in this specialist even a little air on all sides. In addition, the compartment inside has two" for devices up to 11.6 plates "where you have other things can store it separately (eg, a block).
The second bag has 2 pen holder and 2 shelves. Here you can store a mouse, hard disk, charger, pens, etc.. I use the compartment for the charger, an external 2.5 "hard drive incl. Leather bag, and my cell phone charger and headphones. A DIN A5 block takes place in this subject, but can be stored with the in gro0en specialist.
The third "small" trade is still large enough to stow eg. A hard disk or the charger. I use it for USB sticks and other odds and ends.
Besides the two straps which carry a comfortable allowing the bag, a shoulder strap is included. For me, not necessary, but better than need.
At the processing can not be faulted. The zippers work smoothly and give the impression that this will not change anytime soon.
For 13 you get a very well-made bag with good padding and plenty of storage space. It would be difficult to be a bag to find with better price-performance ratio.
