I've searched and really haven't gotten definitive advice on this subject. On a thru hike starting in March heading northbound.
Would I better off with EMS techwick 1 (lightweight) or 2 (midweight) baselayers? top and bottom. These layers would primarily be used for sleeping in.
I don't plan on hiking in them unless its very cold. In that case, I would probably only hike in the leggings and wear my other long sleeve hiking shirt as a base layer.
I could also mix and match, lightweight bottoms, midweight top, etc.
A little more information, I primarily hike in nylon pants and a long sleeve 1/4zip even during the hottest summer months. Both are very lightweight.
I don't really see myself wearing them at all during hiking unless I get cold.
What's your input folks?
