I have this set of 4 neoprene cases brought for my lenses, because on the one hand offer the bag provided virtually no protection and secondly, because in a lens no bag was there. Currently I need only 2 of the 4 have for my lenses, but rather too many than too few. :) The biggest neoprene bag I use the time yet for my compact flash - works great. The material is quite stiff, but also offers thus good protection. The only slight downside is that it's something "difficult", with the drawstring to close the bag completely. Some Vorrezensenten criticized the strong smell of the goods; I seem to have been lucky, or was it because generally improved. Although they smell a little bit, but that amounts to more in regions like the smell of "new car". The processing is as far as I know until now, flawlessly. All seams are sewn clean and complete, the pop-holders and the drawstrings are fine. Compared to other protective bags and lens quivers, with these here, however, only with the greatest possibility to attach it directly to the belt loop by; the smaller the loop is too narrow. As I said, as they are good protection in any case, with the Klip / hook, you can also attach the bag, but I use it only as transport protection in a backpack and storage at home. For nearly 3 per piece you get here simple, sturdy carrying bag that I would buy again at any time.
