Why would you sit in the snow for any length of time? A small foam pad or chunk of Z rest weighs nothing, takes up no space and serves multiple functions. And doesn't make your crotch sweat while working hard.

Wow! Really?? Thanks for telling me about THAT!
Guessing I don't spend as much time "sitting" as you do. Is that the same foam you have on your favorite couch?
Thanks for the profound advice.
