Adding water "resistance" to quilts and sleeping bags

[andrewa]

Having just returned from 10 days in Fiordland, NZ, fly fishing, one of my major gear issues was my quilt ( home made) getting damp from condensation from the tent. The tent issue is unavoidable, but I was hoping to find a DWR solution to my quilts, as both the quilt I used, and my winter ski touring quilt seem to have rather hydrophilic nylon!

Has anyone any experience with Nikwax/Grangers/Scotchguard ect as a means of reducing the degree that condensation soaks in to the outer fabric of quilt/sleeping bag?

It does seem to be an external issue, as outer surface of quilt was dry until I had to fluff around and get out of tent for a pee, during which the quilt touched the damp inner of the tent and got v damp.

I've found Nikwax to work, I've not tried the spray-on product on a sleeping bag tho but I see no reason it shouldn't add water resistance to the outer.
The added weight is going to be much less that adding a highly water resistant cover

I usually use my rain skirt over the footbox of my quilt in high condensation scenarios.. same could be done with a rain jacket I suppose..
