Weight doesn’t change the discussion all that much, other than suggesting tougher face fabrics, with all of the associated problems.
But let’s go with DWR D’s suggestions because he has hiked that trail. My approach would be a Packa in heavy fabric because my experience is that ventilation is reliable while DWR (the fabric coating; not the person!) isn’t. It is the same idea that Roger Caffin uses in the Pyrenees and French Alps.
If you prefer a jacket then maybe GoreTex Pro or one of Frogg Toggs tougher variants. I think Frogg Toggs Action series is a still-lightweight-but-more-durable 3-layer version. Their Pilot series is tough as nails, but heavy. Two pounds for a hip-length parka with lots of pockets.
Jackets don’t make much sense to me in warmer weather because the pack plasters the back of the jacket to your back. However, above snowline, then it might not be a problem.
OR has a military version of their AscentShell that they are making for Ukraine which should be quite tough. Or even PCU/ECWCS L6. It’s GoreTex in military-lightweight, which is like moderate-to-heavyweight civilian. There are L6 overpants as well.
Agreed about spare socks in a plastic bag.
So, again, if you want more specific info then you’re going to have to tell us what you like.
