Santa Cruz, California
I currently have a thin wind shell that felt like the wind is coming through, though it does not. I attributed it the the cool temp's and the high windchill. It was like wearing a drysuit while diving in arctic water, yes you are dry and not wet(i.e. wind proof) but you can still feel the cold water outside of the suit.
I am also looking for a tent for thu-hiking the pct, on previous camping trips I have been on tents of this style have had issues with rain down around the feet. It seemed to be caused by the fly not completely covering the tent where it met the ground. so, just a heads up.
