I'm trying to figure out the best system for staying warm while hiking in cold weather (20s/30s) but still having dry clothes upon arrival at camp. For instance, I'd probably wear a long-sleeved shirt, midweight shirt, fleece and rain jacket to hike during the day. In camp, I'd want to wear my midweight shirt and fleece (and add a down jacket) but it's likely the shirt and fleece would be wet.

How do other hikers get around this problem? I'm trying to avoid adding more weight to my pack so I'm looking for some system that incorporates what I already have (long-sleeved wicking shirt, midweight shirt, fleece, rain jacket, down jacket). Thanks for your thoughts!
