UPDATE!
sketchyourbag - Website with User Interface for giving each bag an unique look. --> You don't have to do something on your own an the quality is still high!!!
Size:- 39 cm x 32 cm x 8 cm

Material:- robust material in carbon look- borders & stitchings in accent colours

Cases:- iPad case- 15,4� notebook case- pocket for pencils- case for books or folders- case for cell phone

Strap System:- slightly angular- 2 straps merge in the front and the back- they distribute the weight evenly on both shoulders

Designs:- every design one can possibly think of- special editions can be made of more expensive materials

The actual position shown in the example was the one  fitting best in our test, but may look different as you wear it.
In the example the straps are in different colours to point out the technique. Actually they�re supposed to be of the same colour.
An update on the positions of the buckles (to adjust the lenght of the straps) will be released within the next days.
