I’m almost there. I’ve worn Smartwool socks for many years (my favorite). I got a nice pair of wool long underwear and have worn them several times this winter and found them much nicer then poly or fleece. Very light weight, warm without being too warm. Washed and dried well and no shrinkage. I added a wool/poly blend top that I really like but am eyeing the all wool tops (Smartwool, Ibex, others). They are expensive but when I find a deal I will probably spring for it. Any recommendations? Anyone else make the switch?
