I'm on the Left Coast and will be hangin in 'above freezing temps'. I have a DIY hammock and a JRB Shenandoah for a UQ. I'm thinking of making an undercover as a windbreak and protect the UQ from splashing rain. I was looking at this material from DYI Gear:
"30d Ripstop Nylon, Metalized reflective coating one side. DWR. 60" wide.
Navy Blue or Green
30 Denier Ripstop Nylon with metalized reflective coating on one side. This material can be used to reflect heat in insulation systems very effectively. You will be amazed at how much heat comes back.
This material is not breathable, so it acts as a vapor barrier, so if used in sleeping bag or quilt systems be sure you know how to manage moisture properly. We have been using this very effectively in making freezer bag cozies with Insultex or Climashield as the insulation."
This would be suspended with shock cord in the side channels and drawstrings on the end. (The UQ is hung on the hammock.)
Will moisture be a problem if the undercover is taken off each morning? Any moisture/condensation would be on the undercover and pool there? As long as there was only windblown, incidental contact between the UQ and undercover (the underquilt isn't sitting in a puddle)...? Will an undercover add a few degrees of warmth to the equation? Is there a more suitable fabric? Good idea/Bad idea?
All thoughts welcome
