Cap 4 question

Find a system that works for you. Comfort and to a greater extent, efficiency, rule in these parts. Boxers may extent the life of some Cap4/thermal bottoms but these decisions often take the number of days out into consideration.

I think the Cap 4 works pretty well as a mid-layer. Where it really excels imo is as a base-layer in high aerobic activities during the winter- in those specific conditions, I like to have right next to the skin so it can move moisture better. If you're snowshoeing, skiing, trail running, etc, you might want to give it a try next to the skin. If the activity is less aerobic, then I think it works just fine as a mid-layer

Thanks guys, I so old I don't know how clothing works anymore.
