Swiss Shield, shows the following graph that indicates the magnetic attenuation falling off at low frequencies as 1/f, about right.
I did not see any claims for extremely low frequencies e.g. 60 Hz. Their material, as far as I can tell, is just ordinary cloth with an interwoven conductive copper mesh. As you point out this doesn't work at 60 Hz, you need some mu-metal.
