Need source for silnylon

You actually have to call Noah lamport to ask what sil they have in stock - it's not listed on the website. It seems like good stuff, and the price is unbeatable.

Polyurethane coating is applied after the material is woven. It is 100% waterproof.
With silicone impregnated nylon (silnylon), the yarn is coated with silicone before it is woven. It has been known to "mist through" during a real hard rain (don't pitch real tight if expecting a hard rain). This is also why camo sil is not available. The colors won't stick to the silicone.

They carry Urethane coated ripstop, but they do also carry silnylon 2nds. The website is nearly useless, other than to get their phone number. Give them a call to find out what is in stock.

For those who have bought silnylon from some of the cheaper sources (<$5/yd), have you been able to distinguish any difference between that and more expensive silnylon fabrics, such as firsts from thru-hiker.com?

MrsMustardman used the Noah Lamport sil to make her asym 12x10 winter tarp, and noticed absolutely no defects, despite the fact that it's supposedly seconds quality.

We haven't had it set up in a serious rain yet, but when it was setup in the front yard for seam sealing, it did rain for a little while, and the ground beneath the tarp was bone dry.

At first the fabric felt awfully light in weight, like maybe the sil coating was extra thin or something, but after actually getting it sewn into a tarp with all the heavy edge binding and tieouts, the weight seemed much more comparable to my OES 12x10 winter tarp. I can weigh both when I get home tonight and confirm whether there's a significant difference in weight.

Wally world in our area still carries the $1.50/yard ripstop in black, brown & green. Any interested?

I've used quite a bit of Noah Lamport sil ($3.00/yd 2nds) in prototypes. I was extremely impressed with the Noah Lamport 2nds and had no issues with it. I got a tiny bit of water bleed through after 24 hours - nothing that would be problematic as a tarp that sheds water. The stuff I've had from them was 67.5" wide. The only blemishes I've seen were very small, barely noticeable blobs of thicker silicone (usually near an edge). Also, one time I was unrolling fabric and 10' in there was a strange splice - the fabric was sewn together and taped both sides.

I now use Ultrasil 1st quality, it has been 64-65" wide. It feels a tiny bit different - it's slightly less slippery (barely noticeable). I've been doing a water test (stretched over cup with water pooled in the fabric) and there has been no bleed through in over 96 hours so far. I expect the water to evaporate before coming through at this rate.

Do you have any idea what weight it is?

What's your source for Ultrasil and how much does it run for?

You can buy it at www.rockywoods.com commercially (~$10.00/yd). If you want a full 25 yards you can get it at Westmark Corp. for a little under $9.00/yd (that's their minimum).

Or you can stick with Noah Lamport 2nds for $3.00/yd.

If you really want 1sts, I think the best pricing is Ed Speer at $8.50/yd. He may even be carrying Ultrasil - I don't know. Definitely give him a call if you're wanting 1sts silnylon though.
