It is not very big, so it is unobtrusive. It has a large map window and more storage space than I need for what I use it for; wallet, cell phone, maps, sunglasses or anything else I want quick access to.
I have the tank protector and then have various tank bag options that attach to the tank protector. I'll try to track down some pictures to post later.
Here is a picture of the tank protector. I think you can easily make out the attachment points for the bag.
Not an FJR Pilot...but I use a FirstGear Silverstone for my tank bag of distraction.
Plenty of room for all my distractions: 3 way outlet splitter (for the GPS, phone charger, ipod (and other misc) chargers), snacks, water bottle, plexus, cleaning rag, wallet, spare keys, etc.
