The Mantona Backpack is a good backpack, no question. The interior layout is variable, the antitheft useful raincover is attending - but unfortunately it is too small. He, I ordered it looked quite large in the pictures, and try hineinzubekommen my photo / film equipment for my next trip around the world, ie: -Canon 550D with 1 medium telephoto, wide angle and a 50mm prime lens one - fits extent. Once then but to get an external flash, a Gopro + minimal accessories and a small but stays lit panel and possibly even a Surface Pro 3 - no chance, especially not to even minimal additional things like a little candy and a sip to drink then to be there the backpack is simply too small and therefore suitable in my opinion for "trekking" under certain conditions - therefore "only" 4 points. If a larger version thereof would I would perhaps even guided by the hand baggage rules strike immediately, so it is just too small for my purposes.
