Are you camping, or will you be able to dry stuff day to day? HUGE difference between camping for 7 days of straight rain, vs being able to dry your stuff at least a few times.
I prefer synthetic baselayer over wool when its really wet. 35 isnt very cold if moving, but its frigid if you’ve been wet for 4 days, its breezy and you have to be sitting for a while. So lw baselayers just for moisture management, pit zips on jacket to dump heat and perspiration while moving, and a insulated beanie, insulating layer or two for when stationary, synthetic like polartec alpha is good, plus something synthetic thats warmer. And good rain gear, full-zip pants and jacket. And pray for sunshine to dry it all out. a lw tarp to stay out of the rain when cooking, sitting, etc. boot driers if possible. Rubber boots worn inside rain pants if terrain allows.
