    Water resistant/proof UQ

    Has anyone made a down UQ with a water resistant/proof exterior shell? I know IX is waterproof, and there are weathershields, but I'm wondering if anyone has tried anything with down. Maybe coated ripstop or even sil for the shell? I'm thinking this might allow the warmth of down, without being concerned about water, and not having to carry an extra piece for a sheild. We get some mighty rainstorms here...

    While searching for other topics, I came across several threads that I would be hard pressed to find again that discussed this very idea. warbonnetguy and GrizzlyAdams both discussed experimenting with a silnylon shell for a down underquilt. The biggest issues were: silnylon acting as a vapor barrier, how to air out the UQ if the whole thing is constructed from silnylon (they had very ingenious venting ideas), and a few others that elude my memory at the moment.

    Those were older threads, if I remember correctly. Haven't seen much on it recently.

    If only the exterior shell is waterproof then you could have serious problems with condensation of the moisture let out by your body. If both inner and outer shell are waterproof then you'd prevent the moisture from even entering the UQ, which I think could be the way to go.

    Yes, my UQ is made with waterproof material, it lofts just fine every time, and I have no vents what so ever. (after all, it does hang down)

    If it did get wet, it would dry out at room temperature, or by clothes dryer. But, out in cold weather, any item is a problem to dry out.
    Never more than one man left behind, so far !

    Unsponsored has sold a few in the UK with waterproof pertex, but I recall all of his being made with pertex of some kind. My UQ is made from water resistant pertex and I have 3 more being marked out now. It sheds rain well, but is still light and highly breathable. I think a few on here use dwr treated UQ's and Tim from Enlightened equipment makes Cuben quilts.

    Hammock Gear's UQs are make with 1.1 oz DWR on the exterior...I'm new to this, so I don't know how much weather resistance this will impart...however, sounds like a good balance between repelling water and breath-ability...

    I've heard that some down sleeping bags are made with a water resistant shell, but I'm not sure what material they use. I can't think of a reason a waterproof fabric would affect the insulating qualities of the down, since thermal transfer should still work just as well through most fabrics, even if coated, and as long as it was a thin flexible material it should allow the down to loft as well as any other. Since moisture kills the insulating properties of down, I would think having a full shell of water resistant/proof material would be the rule and not the exception? Maybe there's something I'm missing?

    I'm looking into the future at my UQ/TQ projects and I know water resistance is something I would like to have in addition to the down. Pertex and cuben sound interesting (if expensive). Thanks for the ideas. Keep 'em coming!
