In reply to sam_craddock:
Guaranteed next years abomination of Gore-Tex will be Active Shell with a Proshell or paclite backer, remembering that Proshell was sold pretty much on the fact it has a fancy new backing fabric that ups the breathability, reduces lightness and friction between shell and mid-layer...
Yet the current Active Shell garments on the market uses the old silver scrim/net backer common to performance shell and XCR, which is surprisingly thick and heavy. I was impressed at the overall thickness of the Arc'teryx Active Shell jackets (so far the only ones available here), they are IMO far more durable than the Paclite jackets out there.
Wait a year and get the next generation of Active Proshell, Active Paclite, Neoshell or Event or something, you will never be able to keep up.
