    How can one tell if a fabric is down proof?

    I've located a source for inexpensive nylon nearby but they are all end-rolls and are not marked. Is there a relatively easy way to tell if a fabric is down proof or calendared (sp?)?
    My initial search on this topic here gave me about 50000 results and I gave up after searching 20 threads. I apologize if this is hiding in plain sight.
    Thanks

    Calendared nylon will be difficult to see through, and shiny on one side...

    generally, if you hold the fabric up to your mouth and you give a hard blow and it hurts your head with no air passing through the fabric, it's down proof enough. the pain you should feel in your head is that of trying to blow up one of those **** clown balloons, the long and skinny kind.
    there are down proof fabrics you can blow through but are normally certified. if you're buying for wally world and you need a fast check, what i describe is a safe bet.

    If you can find a thread count, I think it needs a min. of 250 thread count, or somewhere around there.

    Does down proof mean completely waterproof?

    Down proof does not mean waterproof at all.

    To clarify... Some down proof fabric is waterproof. Some is not. The two terms to do not interchange in any meaningful way.

    IMO the best way to determine if fabric is downproof is buy from vendors who know what they carry. Mill ends and surpluses are great. But if you are going to invest in quality down, don't do the fabric on the cheap. You'll most likely be sorry.
    I may be slow... But I sure am gimpy.
