I read the article on camera bags. Back in 2010, prior to reading the article, I purchased one of the bags that was recommended: CaseLogic Sling Bag. The bag was terrific. However, there is a problem with it and I eventually stopped using it. Due to the mesh backing of the sling, and the friction caused by me sliding the bag forwards and backwards to retrieve the camera while wearting it, the bag ruins my shirts. Do you have any suggestions to remedy this? I would prefer to use this bag again to the new one I purchased (the Case Logic Zoom Holster that was also featured in the article).
