Most of my recoil pads are for lengthening the pull on my stocks, but the one that I use that is for recoil dampening, and is very effective, is a KickEze. They are really soft, don't grab your clothes, and easy to find. You can get the screw mounted kind or a slip on for temporary use.

I found it very distracting in use, and pulled the pad out of the shirt within the first few minutes of use. I still have it, but have never used it again. If I ever want to sight in a .577 off the bench, I may pull it back out. Not disputing Tamid at all, just wasn't for me.
