      I believe that at one time Ed Speer told me that in cold weather
      conditions he would take a 4X9' piece of 1 mil thick plastic that
      weighed around 3 oz. I recall him mentioning several uses and one of
      those was to attach to the outside of his hammock to block heat-
      robbing cold wind when needed.
