I have only recently stumbled across the idea of the 'condensation curtain' used by tarptent (can't find the link now but will add it when I find it) and was thinking about trying to add one to my hexamid.
I have some spare M90 lying about and was thinking about simply adding a couple of guy points from the hexamid and just hanging it from them so it will hopefully divert any stray condensation formed drops form my sleeping bag.
This way I could also use the momentum as a sheet or wrap it around my bag like a bivy if it gets windy.
Has anyone tried something like this before and or have any suggestions?
Also, although it would be super expensive, would M50 work for this application?
