Let's face it, briefcases aren't for everyone. In fact, they aren't ideal for most modern men. Enter the rising rucksack: mixing schoolyard nostalgia and vintage design appeal into one hyper-functional bag.

With the busy lifestyle of today's urban gentleman, there's no shame in stashing your gadgetry and goods in a sizeable city pack.
