So i'm totally confused as to what to get so far as an insulation layer for my upcoming PCT hike. I've been looking at past threads to figure out if i should go with a down jacket or something like a primeloft jacket, but it just brings up more questions. I have a down quilt and have read that it's a good idea to have a synthetic insulation layer as back up in case my quilt gets wet. I've used a trash compacter bag with my quilt on the east coast and have yet to get it wet, so i don't see it being too much of a problem on the PCT.
Then there is the question of the down jacket getting wet, but i don't think i'd be hiking in a down jacket or even a synthetic jacket. Just seems like i would overheat.
I get the weight, loft and expense difference between the two, but practicality-wise i'm a little lost.
Am i just trying to talk myself into a down jacket or should i really look into something synthetic for a west coast thru-hike?
