I'm planning a 2015 PCT thru hike, and it has made an excellent excuse to finally replace much of the heavy REI gear I had been using since high school. I'll be on the trail on April 28. Base weight is currently about 12.5 lbs. I've had a few months to test the gear on local trails and am fairly happy with the setup so far. I'd love your input on anything that should be added/removed.

I'm particularly keen for input on clothing. I've used a sun shirt over a short sleeved t-shirt for rainforest fieldwork and have been pretty happy with it. I may send the sun shirt home after the desert. I strongly prefer running shorts or skirt over pants for hiking, but am considering purchasing a pair of wind pants for cold mornings and areas with lots of poison oak. I'm on the fence about camp shoes – I like trading the trail runners for flip flops at the end of the day, but I'm not sure if they're worth hauling along for an entire thru hike. I'm also debating whether it's worthwhile to purchase an umbrella. I've never backpacked with one before, but I know some people swear by them for shade and extra rain protection.
There's a small chance I could end up leaving with a different pack. I've been having issues with the shoulder straps on the circuit chafing my armpits, but since I like the pack otherwise I'll investigate the possibility of having the strap type changed.
And yes, the camera is very heavy. That item isn't negotiable : )
