I just caught a look at the demo reel video for a new line of Weather treatment technology that kinda has to be seen to be believed. You can check it out on NPR’s website here;
I don’t normally geek out on things like gear construction, but the video is pretty compelling if real.
One great point the article brings up of course is the cost and durability issue. Most water-resistant (I won’t ever say waterproof, solid rubber is waterproof and you don’t make clothes out of that which aren’t designed to handle level 5 biohazards) clothing is treated with some kind of DWR spray which closes the pores on the exterior but still allows moisture to transfer out the other way (think of it like a doggie door for moisture).
No matter how good it is it does eventually wet-out. Seams leak, water gets underneath and most times it actually wets out from your own perspiration. That would still be an issue with this new treatment.
But still; it wets out from the outside too. No amount of current DWR will keep moisture from getting in if you’re getting dumped on for hours and hours. Best it does is keep it off for a longer period of time. At $50-100 dollars for a treatment… if this product isn’t really durable then it may not be market-viable.
But still; watch the video. Some of the stuff they put this treatment through is just mad, and it comes out clean every time.
