just got off the hill for my fifth time. here's what I used in this cold season:
head: buff, wool hat, OR ninjaclava, Julbo explorers, goggles
hands: OR gripper glove, BD Guide Glove, Marmot Expedition Mitten, handwarmers
torso: Smartwool baselayer, First ascent windshirt, REI primaloft jacket, TNF softshell, MH absolute zero jacket
legs: Patagonia baselayer, MH expedition weight tight, Patagonia simple guide pant, Marmot rain pants, MH compressor pant
feet: Smartwool mountaineer socks, Sportiva Spantiks, 40 Below K2 overboots
I wore everything simultaneously at one point (except the gloves), so make sure your layering system works well together. it is a system after all.
