This is the video from Day 1 of the hike. It rained a portion of the day and the Dri Ducks performed well. Stripping off the shirt and rolling the Dri Duck top commando worked the best. I got to a point where I was not sweating and therefore not getting as cold. Hypothermia is a real possibility in temps like this, low 60s-40s, so it is important to do what you can to minimize the moisture. I knew that if I did sweat my shirt and fleece were dry in my pack ready to warm me up.
