I do Mr Silver. I have for years, absolutely love them. They never slide down, they never crunch up behind your knees. When the pants get filthy, pull out the pads and wash. Now I bought the pants without the pads and fashioned my own. I've used neoprene and etho foam. You can also buy a set from the manufacturer. Once you try them, you'll never go back. Extremely comfortable. Mine are Duluth Trading Company Fire Hose Work Pants. They have a heavy grade and a pair I think they call "Lite Weights". I've have both. I'd recommend the lites. At first I thought the lites would wear out, but they haven't yet (couple years now). I also recommend getting the Duluth suspenders with them. Your pants will never droop, slide etc. Much more comfortable than a belt. Just Google "Duluth Trading Company" they're under "work pants" you can't go wrong with these great pants.
