There is an amazing fabric called Epic, made by a company called Nextec.
Things like high end golf apparel would be made of it because it looks like a normal jumper, but absorbed no water and dried in minutes.
Basically, the fibres were internally silicon coated, and then encapsulated.

The US military saw the benefits and started using it. I have a US Army ECWCS Level 7 cold weather jacket made of Epic, and filled with Primaloft. So impressed was I that I have a brand new bagged up one ready to go.
When the US military found out the actual cost of these to make, they soon put a stop to it.
I'm sure I read somewhere that a roll of Epic was a couple of thousand dollars, and that it required 2 different Epic fabrics for the Level 7 jacket.
About the same time the US Army did a plain green Level 7 that was made by Patagonia, and I have a couple of the waffle half zip level 2 shirts made from Patagonia R1 material.
Also have a Level 4 wind shirt in the old digital camo with a Patagonia label in it.
I keep an ECWCS Level 5 in the motor made of Milliken fabric, that is soft, stretchy, totally windproof & waterproof for an hour or so. Probably the most versatile jacket I own, which I think I got new for about $60 in 2014.
Makes the old British Army windproof smock feel a bit cumbersome, but they are still great and good value.
The Yanks have cut costs a bit in recent years, but still on the whole give their lads quality gear.
Gore-Tex is always Gore-Tex & not some cheap shit immitation.
Seem to have gone off track somewhat, so I'll leave it there or I'll rattle on all night.
