Earlier quoted context omitted.

It's silicone (not silicon, as the article misstates) so it's probably safe. Silicone is used in breast implants, home window sealants, cookware (look up silpat) and yes, fabric, as silnylon (the ultralight backpacker's waterproof friend). With the last case, it is not breathable, which is why it's not used for jackets.

I thought silicone in breast implants was discontinued in favor of saline due to the dangers of toxicity with implant leaks.

That was alleged, but IIRC, the studies showed that there was no toxicity, and that the women with leaking silicone implants didn't have a higher incidence of problems than other women their age.

Here are some more details: http://www.neverwet.com/product-characteristics.php They don't mention how durable it is - maybe it rubs off from your car.

If it works similarly to how Rain-X works, it'll last for awhile, then eventually you'd need to re-apply it. Rain-X is pretty cool stuff. You can drive down the road in heavy rain, and not even need your wipers 'cause rather than spreading out when the rain hits the windshield, it beads up, and "rolls" up the windshield over the car.

If it works like Rain-X without causing the streaks that show up painfully in sunlight, that would be a pretty big deal.

Not to "rain" on their parade (heh), but the ability to pass water vapor effectively while also remaining hydrophobic for water droplets, and doing that for a long time on surfaces that are exposed to constant wear, is sort of the holy grail of the outdoor gear industry. The company's page for their product ( http://www.neverwet.com/product-characteristics.php ) doesn't mention breathability. Considering that breatha…

I love the graph on that page, where 160-175 "degrees of hydrophobicity" are illustrated as a huge, exponential increase over 110 degrees. To me, more than the breathability or durability or whatever other technical issues, that graph is a huge red flag that this is 90% marketing, 10% engineering.

Actually the graph states that 90 degrees is the zero line because anything less doesn't count as hydrophobic. The whole page in fact explains what the graph means.

They describe 'wet' as having a liquid on the object its used on. I wonder how the object feels with this applied.. ie. does a glossy object feel rougher

Not necessarily. Surface roughness that creates the most hydrophobic surfaces is around 0.1-1 microns which is much less than the width of a human hair.

It still used a lot. And they still leak.

Helmet visors, too... there are some products out there for them, but these demo vids have some really impressive performance and look like it would work a lot better in fine mist.
