Think cool, no direct sun, rain, MUD
Quick drying shorts ---- I would wear long pants/zip-offs. You aren't going to get a sun tan on this trip :)
Syn quick dry t shirt ---- just wear the Capilene
Smart wool socks/liners
Keen vortex boots
Pack lite vortex rain shell
Silk/wool Baselayer shirt ---- nix, you have the Capilene
Gaiters--- shorties are good for mud; long ones nahhh, unless you are getting up on the glaciers or snow up top.
Fleece pullover --- yes (no if you take the parka)
Thermawrap parka --- no if you have the fleece. Perhaps a light vest?
Fleece pants (in camp)?? --- nix. Rain pants and long johns. You'll be under shelter soon enough.
Dry socks for each day --- maybe --- how many days? No more than 2 spares.
Polartec socks --- nix you have all those dry socks
Capilene pants and top --- good, but I would be wearing Cap1 all the time. What weight Capilene? Lighter stuff is great under your rain gear. Wear the Cap1 and your fleece.
Do I need extra set of shorts/t shirt. ---- No, but a dry base layer top for sleep and spare
Capilene 1 LS top
Zip off pants
Power Stretch hoodie
Patagonia Micro Puff vest
1 extra socks
Capilene 1 long johns (sleep too)
1 extra top (dry and sleep)
Seattle Sombrero rain hat
Patagonia Rainshadow jacket
Marmot Precip pants
Mont Bell short stetch gaiters
Gloves -- Mountain Hardwear Tempest shelled gloves for rain, or SealSkyns
If it is raining constantly, the pants come off, the light long johns and rain pants go on and stay on for the day. Alternate tops to suit your comfort. For a wet trip, the windshirt is wasted really, as are the zip off pants. I might wear a Cap2 weight top under my rain shell and I would want a dry base layer top for camp/sleeping, but it would light stuff to wear with the Power Stretch. A Power Stretch or 100W fleece vest can be nice under a rain shell in cold/wet stuff.
Take a sit pad--- there won't be a dry place to sit, anywhere, ever. I use a Z-seat and extend my sleeping pad with it.
