Genius idea
This is an absolutely genius bag. I have just taken it on a tour of South east Asia, ostensibly as a bag to take out in the evening; however in inclement weather when I needed to carry an umbrella and a lightweight jacket it was so easy to covert it to a backpack with more space. I felt totally confident using it, it felt secure and several times I secured it to a table or rack. I like that you can access the main compartment from the back zipper. It is genius idea to convert from bag to backpack and I'm really pleased with my purchase and would recommend it.
