Aah, such a comfortable cushion with no slip

I have been using the Max extender bought from Amazon and it is pretty much the same as the more expensive ones. It works quite well, but with the usual problems of slipping when not too tight and hurts when it is tight enough. I used a variety of foam wrappers, gauze etc. But nothing was easy nor fully effective. The I found this-

I cut off the top of a cotton sock, slit it at the top over 1/2”, slid it over the cock. Put the extender on with the slit sock material spread between the extender seat and the testicles and the belly, and the sock tube over the shaft. When I put the front head piece on, I wrapped it around the penis and tightened the belt.

It is tight, does not slip and feels soooo comfortable.
