Lowepro Pro Runner 300 AW
Just a quickie - my Lowepro Pro Runner 300 AW fits in my Lowepro Pro Roller 2 with room to spare. And here's the proof!
As you can see, it fits across the narrow dimension with room to spare. I was on my way to a job and just could be bothered to move all my kit between the wheeled Pro Roller 2 and Pro Runner 300 AW. At he top of the bag is a whole load of off-camera Strobist gear including a couple of imitation Manfrotto Nano stands. The Pro Roller 2 is a very versatile and durable bit of kit. I've had this one for more years than I can remember. Buy quality and it will serve you well. Buy cheap and it will end up costing you more as you have to replace the item sooner rather than later.
