Silnylon as VBL

Edit: Just answered my own question; in the comments to Andrew Skurka article on VBL's, it's mentioned that he used silnylon to make his clothes.

I noticed on another thread where Lynn said she made VBL clothes out of cuben. Can silnylon be used for VBL clothes as well? I've been meaning to order some 2nds silnylon to practice sewing before embarking on making a down quilt + insulated pants. If I could actually make something useful as practice, that'd be great.

I need VBL clothes because I plan on using my insulated clothes as part of my sleep system, which rules out the VBL sack I already own.
