I have been looking forever for a backpack that had security features without being a massive laptop bag. I wanted something that was small enough for every day, but had a little bit of extra space for day trips to fit things like sunglasses case, my iPad, that kind of thing.
The mobile phone pocket on the back is great and I love the fact that I can lock the main compartment to an extent so when I'm somewhere more crowded I don't have to worry about someone grabbing stuff from inside there.
The only two things that could have been better are:
1. The straps are a bit long. I'm quite short (160cm/5'3"), so even at the shortest setting they feel a bit loose and slippy. If I could have shortened them by another inch, that would make a massive difference.
2. The zipped pocket on the inside would, for me, have been so much better if it was placed against on the front of the bag rather than the back. If I'm carrying something like a tablet or a small laptop, it is much more comfortable if they rest against a flat back of the bag.
Other than that, really pleased with it.
