I'm looking at Thru-hiker.com's fabric choices for sale, and I'm confused about "silicone Impregnated
and "Silicone Coated". There is "SpinnTex Pro .8oz Silicone Impregnated Ripstop" for sale, but I was reading Ryan Jordan's article that says
"Silicone impregnated fabrics must be distinguished from silicone-coated fabrics (commonly referred to as “silnylon”). Silicone-coated fabrics are not breathable and are used in applications where lightweight waterproofness is required, such as tarps and bivy sack floors. In contrast, silicone-impregnated fabrics include those for which their water resistance is achieved without a laminate or coating…" etc.
Are there two types of SilNylon? Is it impregnated or coated?
Also… has anyone purchased from Rockywoods Outdoor Fabrics before?Aug 17, 2007 at 2:50 pm #1399046
And what is the manufacturing difference between "1st quality" and "2nd quality"? Do I not want to go into the woods with a 2nd quality fabric bivy?Aug 17, 2007 at 4:57 pm #1399058

Silnylon is made for the parachute and hot air balloon markets and the standards for firsts are very high, including not having too much coating.
I have used Thru-Hiker's silnylon seconds for for a shelters for several years now. No problem. (and it does rain where I camp)
I think what Ryan is calling silicon impregnated is fabric woven from thread that is impregnated with silicon. The threads themselves won't absorb water. It makes a somewhat water resistant and somewhat breathable fabric.
Silnylon that Thru-Hiker and others sell is high quality nylon fabric that is then treated through and through with a silicon sealer of some sort. Fairly waterproof but not at all breathable.
I have not bought from Rockywoods … have never felt the need to buy from other that Thru-Hiker except in the rare case where I needed a particular color he did not have.Aug 18, 2007 at 9:03 am #1399110
When you purchase your SilNylon, do you get the 1st quality or second?Aug 18, 2007 at 9:59 am #1399113

Seconds …. unless I need a color that is only available in firsts (as when I wanted a blaze orange pack cover)Aug 28, 2007 at 4:09 am #1400205

I recently ordered some ripstop for Rockywoods. The order came in 2 days. No complaints!
