These bags are the perfect size for keeping automotive tech manuals in your vehicle, and the small pocket on the front is also the perfect size for most owner/operator manuals, receipt wallets, notepads, or small forms. The elastic pen loops can be used for small tools, a tire pressure gage, and of course writing utensils. I have one for each of my vehicles and would recommend it for any person who likes to work on their own vehicle and maintain it by the book. I would give 5 stars except that design has one flaw. It's not possible to snap the flap shut when the bag is full, as with a two-volume tech manual set. This can be remedied by adding a second pair of snap-button studs about two inches bove the two studs already provided-that's what I do. This allows the flap to be securely closed whether the bag is partially or completely full. Also, if used frequently as a shoulder bag, the strap would be better if provided with a slip on pad like Rothco's "All-purpose Shoulder Strap with Removable Pad", or if the strap were wider like Rothco's "General Purpose Utility Strap". I think Rothco would do well to incorporate a second pair of snap studs in their next revision of this pattern so users can get the full use of the bag's volume, and I would recommend making note of the potential utility of this bag to off-roaders or vehicle fleet managers in descriptions.
