Bag recommendation needed for a Gripped Canon 60D and 28-300 lens

[mugsandb]

I have recently bought a Canon EF 28-300mm f3.5-5.6 L IS USM lens. It is fitted to my Gripped Canon 60D. Can anyone recommend a bag just to hold this set up, please?

I thought that the Lowepro Toploader 75 AW would be ok, but is just a bit too small.

I have a Lowepro Pro Runner 350 AW for all my equipment, but I could do with a separate bag just for the camera and 28-300mm lens.

Thanks

Andy
