Spruce;

The rain pants as wash day wear is what I did. Also used them about three-four times as an outer layer in a cold, windy camp, and twice I slept in them.

You will certainly need the windshirt. I use mine with a down vest from WM, and it's good down to about freezing. But the hardshell would do the same job, and handle colder weather, but would be considerably heavier and bulkier. You don't need both. I think you're on the right track.

I will repeat the advice to use pymetrin on outer clothes. I forgot. Did you mention a bug net for your head? You will need a hat to keep it away from your skin all the way around, and black is much easier to see through. Best, jcp

PS: Brian's advice re. guidebook pages is on the mark. I carried just the maps and pages from guide that I needed to next post office stop. Also carried a shirt pocket style wire bound notebook with half its pages taken out, along with a stub of pencil. Found them very useful. jcp
