Received this bag today.  The entire exterior is made from high quality, heavy gorgeous leather - smells so good.

Not fond of the closure on the laptop portion - the top strips are vertical, the lower strip is horizontal.  They don't stick together well at all (see pic).  Also not sure what the leather strips inside are for.

But the quality of the bag is so nice, the leather gorgeous and it has so much room. It's exactly what I wanted, and I love it.
