But if you want such a camera bag not to use - for example, because in the big city too conspicuous - or want to be transported protected items at different locations, then was formerly the solution: wrapping the device / accessory in a sweater or a towel.
The Novoflex-wrappers I use as a practical alternative - eg for lenses or my camera when I am taking them in a normal Daybag. The cloths are made of 3mm thick, blue, elastic neoprene material. The outside is completely fibered, so that the four Velcro straps that can be found inside at the four corners, are "attached with velcro" anywhere on the outside. Thus, any bags / cases for a variety of photo parts can be folded and fix it. (As I said - I use them eg for lenses, my little ultracompact camera, my small external USB hard drive, or sometimes for a SLR camera with a short lens.)
The 3mm-padding absorbs smaller impacts and collisions in the backpack well enough, and the flexibility of cloths means that I - must struggle can use for various photo parts, so that I am not with special containers (separately to purchase) - zurechgefaltet as needed ,
Tip: Before I buy a wrapping cloth, I measure with correct size piece of paper, what size do I need - the Velcro does not take much overlap, but wait just a little.
