Well, while we're on the subject of what wool we wore, here's what I wore for my snowy hike today. Ibex Loose Tights on the bottom, and on top, an Icebreaker midweight zip-neck with a lightweight Icebreaker tank underneath and an Icebreaker vest over top. Also a Smartwool lightweight hat, wool mittens, and wool socks. I would have worn a pair of my Icebreaker boy shorts but both were in the laundry. The only non-wool pieces of clothing I had on were my sports bra and shoes.
