Brainstorm: Tyvek + Never Wet?

That's funny Cesar,thanks for making me laugh :)

I like it :)

Tyvek 1443 has a hydrostatic head of 7622mm while Tyvek 1460 is 1270mm. That is enough to stop most rain.

Tyvek is made from polyethylene which is naturally hydrophobic. Neverwet is Superhyrophobic and probably will not change the hydrostatic head like all other DWR treatments.

Adding neverwet to tyvek will probably not make much of a difference. It will however add weight.

My take is that anything you apply to Tyvek will reduce its breathability and if you do that then you've destroyed its best quality. I agree that Tyvek 1443R–the material we use in the Sublite–is remarkably water resistant. However, it does absorb some water and takes much longer to dry out than a coated fabric. For that reason you would want to think twice about using it in wet environment, at least if you intend to carry it.

Yeah, I can see why one would not want to spray a Sublite considering the issue of breath-ability–thanks Henry. A tarp on the other hand, I would still be interested in seeing if this would be an effective thing to do. While Tyvek is very water resistant, NW could in theory make it waterproof and unable to absorb any water. And cheap to boot.

Just a brainstorm I had. I am surprised there seems to be not as much experimentation with NW now that it has been on the market for some time.
