I bought this for an upcoming trip to Italy because I plan to hold on to my goodies.
I figure that it will take some effort to get inside because of the clever zippers and
special mesh in the front panel. The straps have thin steel cables inside and lock so
that should also be a good deterrent. Just try to cut and run you pesky devils.

Back from my trip to Italy and must say that this bag was perfect. I jam packed it and
it still had more room.  Because of it's small appearance I only had to check it once at
a museum. Because it's pretty much theft proof I was able to enjoy myself without
being overly concerned about having my belongings stolen. I highly recommend this
back pack. It's called Pacsafe fo a reason.
