Here is a Christmas idea you could leave laying around in hopes that it appeared under the tree. I got this catalog in the mail and found these beauties. $22 per pair are similar to Carhart double knee. Bought three pairs. Can’t find a source for the knee pads so I used 3/8″ closed cell foam. Soooo nice. http://www.sportsmansguide.com/cb/cb.asp?a=161212
I have no financial connection with this store.
Enjoy,
