Softest UL nylon or poly for quilt interior

[Troy Ammons]

What is the softest most comfortable UL nylon or poly for quilt interior?

A couple of years ago I picked up a swatch of Pertex Quantum material from someone here on Gear Swap. I like this material for use in wind shirts, for the way it sheds moisture and also wicks it away. It also feels great against my skin. As it turned out, I used it cover the top and sides of a MYOG +40* quilt made from one of those cheap Costco synthetic throws. I figured it would help shed a bit of moisture from a light rain shower if I’m not in a tent.

I don”t expect that this will help you much in your stated quest, but it is a very unique material, albeit a bit pricey.

I just used membrane nylon 0.66 oz for quilt interior.  Comfortable enough.  I would use it again.

Where can I buy Pertex Quantum?

Momentum 50 from thruhiker.com would also be an excellent choice. Premium quality and is 0.7 oz per sq yd finished weight.

Monte and I agree :)

I bought some pertex fabric from some company in U.K. a few years ago

I have a quilt built with thru hiker M50 and would prefer to find Pertex.

This 7d fabric from AdventurExpert is surely the softest, but isn’t downproof. Another reason to go Apex :)

The 7D fabrics from Adventurexpert is really nice, it feels like silk. Not downproof, but it works with synthetic insulation (apex). I made a sleeping bag lined with this material this year, and i like it a lot.

Another nice feature (for sleeping bags) is that it’s less slippery than conventional lightweight nylons, so the bags moves with me when I turn, keeping the opening against my face all the time.

I did a 5.0 Apex quilt from Thru-hiker materials several years ago.  I can’t remember if I used M50 or M90, but it’s by far my favorite material due to its softness.  I think the Momentum fabrics from Thruhiker are really underrated these days, probably due to the popularity of RipStopByTheRoll and other more popular online fabric sellers.

I’ve since done a few other synthetic quilts using RipStopByTheRoll materials (A 6.0 one for my grandson, and a 7.0 one) and neither compares.  Same with my wife’s 18 month old down quilt from EE and my 2012 down quilt from EE.  I like the Momentum fabric so much I want to do an Apex 6.0 out of it.  Maybe this winter when the nights are long.

Does Momentum have ripstop? I’m guessing not, I think taffeta weaves with no ripstop are softest.

[Jeff McWilliams]

Thru-hiker lists their Momentum 50 and 90 products as “Mini Ripstop”.  I don’t remember if that was always the case, or if years if used to offer taffeta options as well.  I think they did at one point offer “Momentum 90T” which was a taffeta version.  So now I wonder if what I used to build my Apex 5.0 quilt was 90T and not 90MR.

Troy, our 8d taffeta nylon comes in around 0.63osy finished weight and is quite soft.  Definitely doesn’t have the more plasticky feeling of M50.  Shoot me a PM and I’ll get a sample headed your way.

Jerry’s U.K. Pertex company was bought by a Japanese firm a few years ago. Troy, if you Google “Pertex Quantum” you can get to that company quickly.
