      Hi Ray

      If I follow you your pad is 2.5' wide and 5' long and open in the
      middle. Did you consider baffels of any kind. It seems the down
      will want to congergat at the center and leave the perimeter thin
      but I don't know. Are you still using your HH and if so is this pad
      for it? How will you attach it? I'm picturing it running diagonally
      across the hammock bearly covering some of the entry slit.
