GnomeBuddy, I am going to order my EVA pad from the following site I think:
I am going to order a 1/4" thick pad that is 40"x80". I figure that I can cut the pad some if it is too large but I think that the added width will be good for the shoulders. The longer length will be good for the head and feet in cold temps maybe. If anyone knows of a better pad with the same approximate dimensions, please provide me with the information for it.
