Previously I had bought the wrapper for lenses. With the large version, I can easily hit the camera with lens and store in my normal backpack. Use it now for some years and never had any problems. At first I was a bit skeptical because the Velcro straps keep really tight, I was a little afraid that I have to spend too much power and reminds me a bit down. This was not so, you get used to it. But they really hold up firmly reliable.
Positive is the thickness of the 'fabric', here we offer really protective. Others were me here too thin.
