Practically-beautiful City backpack with defects

I own the City backpack in black since May and have it in daily use. He is as well-synthetic, very light, looks good and actual as already described by others through its division for me very convenient (a total of 3 large compartments, here fits among others a Kindle od TB into;. 3 small and 1 inside pocket , eg for ID, etc.) I wear it almost exclusively through the shoulder, yet the average, rarely used single handle already in disarray, that the narrow band Synthetic is where it is held by the fingers on the inner side, completely detached. Very very unfortunate material here is too thin / unfit.
I hope the rest of the bag does not lose even their thin shell!
Supplement: the nice City backpack I must now replace: Since September (after 4 months) broke up at every turn, the (synthetic) material, since it looks tattered and is no longer "public useful". I am still looking for a similar design and practical shoulder bag ...
Too Bad !!!!!!!!!!!!!!
Since I have no comparable practical and lightweight backpack found, I bought in October the same again with the same appearance, stable material (ie no longer as soft, yet pleasant), this time "Made in China" and 10Gramm easier! He keeps hopefully longer - I will report!
