If you want some of this nasty-ass fabric, the best place to get it (that I've found) is Perfect Fit-McDonald. They also have nice Cordura at a reasonable price.
I'm also never ordering vinyl-coated polyester ever again. That stuff stinks a lot, too. And isn't too great for you or the environment. But really, which synthetics are. The question is: which is going to do the least amount of harm. I'm sticking with an acrylic-coated poly for my weather-resistant liners..for now. But who knows what kind of foul things that contains.
Appropriately enough, some manufacturers are going PCV-free with their designs. And there are groups out there promoting eco-friendly technical fabrics. I just have to find their sites again. Ha.
Get the hell outta here!
