I'll be on the NC section of the AT in early April. Temps should be 30-40s at night, but could dip down.
I understand I need an insulating layer beneath my Golite Virga jacket.
Would a thin wool sweater work well? I also have a button down flannel that is 80% wool, 10% poly, and 10% acrylic. Would one of these work?
Under this I'll have a lightweight wool tshirt and light poly thermals.
Being from Florida makes this REALLY hard to figure out.
