This backpack is perfect for when I'm in my work-travel mode. It enables me to carry everything essential, and be carefree in knowing that my valuables are protected. I was surprised at how voluminous and scalable its space compartments were. The design is extraordinarily brilliant - it stays compact regardless of how much I stuff it with items. All the safety features are world class, and my search for the safest compact backpack ended with this product. Three cheers and thank you, Pacsafe!
