The stuff had cosmetic problems right out of the block. It was crankily for one thing. For another, it tended to turn sort of grayish, which didn't have any impact on performance but didn't look good. And then some of the dots would either migrate or fall right off, which again wasn't a huge performance problem but didn't inspire confidence. Gore fixed most of these issues in subsequent versions. But PacLite's worst sin that it was very nearly as expensive as regular Gore-Tex, yet by Gore's own admission lasted only about half or two-thirds as long, depending on usage. Understandably, once consumers learned this they started to question the wisdom of forking over $350 to $400 for a shell that might be toast after a couple seasons.
Last year Gore itself more or less killed PacLite itself by introducing Gore-Tex XCR, which was lighter and more breathable than its previous material, and used the same two-ply/three-ply construction methods that have been proven with earlier Gore-Tex. So the market has split between XCR at the high end, and various makers' proprietary waterproof-breathable fabrics at the middle and low ends. Some PacLite garments still are out there-L.L. Bean makes quite a nice lightweight shell called the Ultralight for $249 that uses PacLite-but it's fading away.
