one I sought

This bag is simply parfais. My MBP 15 '' is well protected either have level of the screen in my back or the bottom bracket (below), but also right inside the bag. multiple storage perfectly fit me as well as big side pockets or I can store a 1/2 liter bottle. I have not yet tested the rain cover (I'm in no hurry either :-)
The only "problem" I was meeting with his pockets and storage, I must be careful not to over fill ...
I advice to all those like me who are heavy use, which works with and for others too ...
