    Possibly dumb idea...

    Could you sew tyvek and use it as one layer (either inner or outer) of a down underquilt? Is it important that an underquilt be breathable? I know folks make "protectors" so could you make the outer shell out of Tyvek and have a shell and protector all in one, then make the inner shell out of 1.1 ripstop?

    One of your main drawbacks will be compression and compressability. #1, the inflexability of tyvek may actually compress the down, not allowing the down to loft. #2, packikng the UQ will be difficult as it tends to do better folded than stuffed.
    All said, others may have a different opinion, HYOH.

    Do you mean the tyvek does better folded than stuffed?

    I've washed some tyvek and it's really soft now. I was more worried about moisture.

    I would be, too. Experience has shown that breathable fabric works well for underquilts, don't think I would put in that much time and work just for the experiment.

    Breathability aside I'd be more concerned with loosing down from it. Tyvek doesn't hold up the best to sewing and you'd need to tape over the seems to prevent loosing down through the stitches. This would just add more weight and cost to the UQ.

    I've got a bunch of kmart pillow down and all the other materials on hand if I use tyvek. You might be right about the time it'll take though.
