Practical bag with default (acceptable)

3/5 because corresponds to the description.
I removes for: the strength of the bag fixed by simple scratch on the main strap, it will not have to put weight into it ..
And less a star for: black really makes a light brown.

I like: matter and finishing are correct.
I like least: the main strap that has no solid surface. The mobile phone pocket on the front, not adapt to smartphone, because far too little. (Smartphone 4.3 "= too).

I recommend to transport less light object has 5-6 Kg.
In case of heavier load port I do not recommend.
