The Maxpedition Falcon II main compartment rear top has a little hanging loop and a bit of velcro. I presume this was meant to afix a hydration pack here… but is there a laptop sleeve which would particularly fit here creating a hanging sleeve, well protecting the laptop? My laptop is 13.25 x 9.15 x 0.79 inches.

I could jerry a slipcase like https://images-na.ssl-images-amazon.com/images/I/71YbG8k8rxL._SL1100_.jpg roping the little loop and the handle together and use sticky backed velcro… but something made for here would be (much) better.
