This bag is a great bag if you want something completely secure. With the combined effort of Velcro and to buckles on the outside its impossible for anyone to get into the bag.

The inside of the bag is a little smaller than I expected it to be. If the sleeve for the tablet wasn't inside it might be a little better.
The shoulder strap is great except for the padding it comes with. The padding is very uncomfortable and I ended up taking if off only after two days of using the bag.

I do love all of the pockets inside, I found one the other day that I had no idea was there and I have had the bag for a few months now.
