I figure a wind shirt will do for me most of the time.Poncho vs Raincoat. Its probably even debateable if either are needed for a large portion of the PCT. I liked having the raincoat in the windy mornings a few times in the Sierras... I wore it for about 3 hours cumulative for mist the entire trip...but we had outstanding weather. If it is cold, its a nice extra layer.
Good to know.With the Sierra cold...it wasn't cold for me during the day. And in the evenings, I just hit the hay if it was cold...but that didn't even happen much.
I just did 19 in the Smokies with a full pack, so a 20 mile slack might not be too bad.Depending on the timing of your start, you can slackpack the first 20 miles. That'll work if you go to kickoff. There are people who will take you to the border in the AM and you can just walk back with minimal gear.
