Excellent workmanship, nice design, very practical. I especially like the very solid, sturdy zippers, the compartment for valuables directly on the back and the clever design, the lay strap so the laptop compartment that potential thieves, it definitely can not open if you have the backpack on his back. That a chest strap is missing, is not bad. This backpack is not already used for long hikes in the mountains. I highly recommend this part.
