I have yet to work with down but I plan to soon. I need some help on down proof fabrics. I have lots of DYI fabrics and netting at home.
What constitutes downproof? Is there an easy / eyeball test?
I have 1.1 DWR ripstop, and I am pretty sure it's downproof based on everyone else's UQ. So I should be good for the shells.
For the baffles on the UQ and TQ, I am considering mosquito netting. I have several different types of nettings on hand with very small holes. I don't know the names of any of them.
How can I determine if the netting is downproof? OR should I just use the ripstop for the baffles?
If I use the netting, do I want it "stretchy" or fairly firm? My thoughts are "stretchy" baffles are less likely to tear, but I don't have anything to base this on.
