> Zero breathability (just like Gore-Tex in practice!) but because designers know this, they have excellent vents added, with waterproof zippers to close in extreme weather. That's not a distinction. Most Gore-tex or similar proprietary brands also have vents and waterproof zippers. In fact, for the vast majority of readers here on HN, pit zips and a storm flap on a seam-sealed jacket will keep them dry and keep the garment from wetting out in the vast majority of conditions. Heck, they could probably even get away with one of those super-lightweight packable windbreakers with a DWR from Mountain Hardware, Patagonia, etc. You could be out for maybe 25-30 minutes of driving rain before water finally gets in through the seams. That's more than enough time for most indoor cats here. :)
