The Smartwool Active Fleece Wind Pant puts a windproof front panel rated at 1 CFM behind a non-PFC DWR finish, so a cold headwind doesn't cut through on the way to the trailhead or the chairlift. A merino layer sits against the skin for warmth while a durable synthetic shell takes on the wind and rough weather from the outside, with a merino-lyocell lining adding another layer of soft insulation underneath. The body-skimming athletic fit and flatlock seams keep the pant moving with a stride instead of chafing against it. What Our Gearhead(R) Experts Are Saying:"I run hill repeats in these on the coldest mornings of the year, and the front of my legs never goes numb from wind the way it did in a plain fleece pant. They go straight from that workout to standing around after skiing without ever feeling like two different pieces of gear."
