Elephant Tank Bag Organizer

this works very well. however it should be included with the bag purchase

I bought this primarily to complement my BMW GS tank bag which is a cavernous crater in which small things get lost. The eyeglass compartment isn't that well fitted and has no protection; not enough room to store glasses in a hard case either. The cellphone pouch can't fit an iPhone 5 with a case, only big enough for an iPod Mini, and strap on it is totally useless (too short). The pen pocket isn't wide enough to hold a mini flashlight, only slender pens. Beneath it, the pocket can fit unfolded money bills (yay) and opposite in the zippered pocket you can hide a passport securely and a few other things - but then don't expect to fold the wallet back to closed. The driver's licence (or credit card?) window pocket is too tall and not wide enough for standard card dimensions, so things fall right out of it. Overall, good solid construction but not as practical as you would think - you can make your own probably for less money.
