It was a moment I was looking for a bag incorporating these three possibilities, because it is not very common ...
For now, it seems to hold the road even with heavy loads, because I also serve to make food shopping and I can go 4-5 soda bottles 1.5 L and it is space for web Other foods: to do over time, in particular to the telescopic handle Alu ... ^^
Only the straps as a backpack are not particularly comfortable (no padding) not very ergonomic, but good for the price ...
I have not done the test, but at first, it might contain a laptop 17 "I have taken the mine by comparing with the official dimensions and it should go without too many problems ... A check anyway ...
I hoped to have a few more pockets on the side, but hey I will not be choosy.
To date, I have never been disappointed by products of the brand PORT Designs as a laptop bag, and this one is no exception to the rule!
Price / quality excellent !!!
