cloth, usually sell for about 20 bucks a pair I think. look on ebay for them or other reseller. plain black would be nice, no lettering, at least for me. =D

 

Rick,

They are made of Nylon with a foam cushion inside and wrap around the belt and hook with Velcro.

They are intended to stop the belt from cutting into your shoulder. I find them uncomfortable and don't use one for it's intended purpose but do use one on the passenger side to stop the buckle from rattling.

I paid $12 - $14 for mine.
