It’s like a bullet-proof vest for your back. Only not bullet-proof. No, this won’t cause anyone any concern. You just look like you are part of some covert op and wearing your gear. I’m sure it won’t raise any eyebrows at the airport or the bank.
On the plus side it goes with anything you might care to wear. Hell, why not let your spine handle the load? Especially if you have an old clunker of a laptop that has caused you some arm injuries. It has 3 compartments. One for your Laptop, one for accessories and a pocket.
