I own a small company that distributes medical implants from a few manufacturers. The amount of material required to bring to a case is sometimes baffling. The Barrage Pro will hold three full surgical trays plus a laptop, scrubs, iPad, cords etc. Its configuration is nearly endless. I've used 2 for 6 years now and they have worn well. I had to stitch one, but honestly, the weight I was putting in it was probably 70lbs and I'd grab it by one strap and swing it onto my back. It was one of the first purchases I made when I set up the company and it was a great choice.

As a industry representative, there are all kinds of other solutions big manufacturers have given to their employees. Mine looks nothing like theirs. It also gets a lot of compliments, especially from guys who ride. Also, as an aside, I found the seatbelt/keychain was really helpful. You don't get to carry your keys into surgery. I never have to wonder where they are.
