Chill the economy version of a great bag

The Retrospectives of think tank are already great pockets, irrespective of its size. The show yes the numerous rave reviews on Amazon, Youtube etc.
Compared to the Pinestone- and Blue Slate variant Thinktank processed at the black variant, a upper made of synthetic fibers, the smoother and thinner than that of the other variants. Thus, the black variant is indeed around 150g lighter, but subjectively it feels even after searching "less" to. I personally like haptics and material thickness of the other variants much better. By thinner compared material, the cushion of the two straps from falling correspondingly thinner.
It has also been dispensed with in the black variant on the sewn-in carabiner unceremoniously and eyelets for fastening and length adjustment of the handle are made of plastic (instead of metal as in the other versions).
All in all, this bag seems to me as if Thinktank attempts in the black variant, to save on material, in order to optimize the profit margin a few percentage points (Caution - subjective impression).

Finally, I give back the black bag and keep the Pinestone variant.
