I bought this bag to use as a carry-on flying with Delta (maybe irrelevant, I know the containers are all supposed to be standard sizes, but we all know how that goes).  It worked out great!  Plus the flight was full so we were bursting at the seams so to speak.  The bag seems to be made out of great quality, and has plenty of stuff that men love, zippers and buckles and such.  If you want to use this as a "patrol" bag, I believe it would be effective for your quick grab sort of items.

I have not had any material defects or anything at this time, and I put a great deal of stress on the bag, so, it's definitely worth the cost.  I would recommend it.
