Mulberry: Two bags in one!

Once in a while, it would be interesting and probably more practical to carry a briefcase by relieving your right (or left) arm with your two shoulders instead - not to mention if your briefcase is way heavy. Your iPad, keys, wallet, planners, notebook, phoneS (emphasis on "S" for those carrying more than one phone -LOL) and tons of stuff including the bag weight itself all add up for that "strained arm caused by carrying heavy briefcase experience". 

I hardly see dual function bags in men's line of bags. The Postmans Lock Backpack from Mulberry undoubtedly will not leave either of your hands much occupied as you can still hold your hot cup of coffee while carrying your briefcase behind your back. 

Mulberry bags are highly distinctive for its single flap closure with two belt-straps (in some designs) and buckle detail.
