I saw the writeup for this product and decided that since I would definitely be buying new camera tech that would need extra protection I would give this wrap a try. I'm glad I did because it is far better than the faux leather pouch that came with my latest new lens and I can rest easy knowing that the lens is not only protected in the camera case but that it is extra protected by having this wrap around it.
According to the sales material the wrap is a 17 x 17 square piece of "polymer material" with "nano-technology" to bond with itself and stay closed with great "bonding force." The quoted material was lifted from the sales material and I don't know what they really mean other than to say that the cloth will roll together and stay closed with strong adhesive force. The sales talk, in that regard is true - the material does stay closed although I am not sure why.
The material will also, it is claimed, clean the product in contact with its fuzzy inner side. That too is true. I have wrapped my Nikon 750D and, at a different time, my 400 - 800 mm telephoto lens. In both cases the adhesion was strong and the equipment felt secure wrapped in the cloth and came out cleaner than it went in..
So, does this material work totally as claimed? Is it worth the cost? All I can answer is in a totally non-scientific manner, that it seems to do exactly that. So, I rate this material as a 5 star product that somehow fulfills its sales hype.
