The Smartwool Active Fleece Wind Headband puts a windproof front panel between your forehead and the cold, while merino wool handles temperature, moisture, and odor the way it naturally does. Stretch fabric keeps the fit secure through a full run, and flat seams stay out of the way instead of rubbing at the temples. An ergonomic shape covers the ears fully, and reflective details add visibility when daylight runs short. What Our Gearhead(R) Experts Are Saying:"I've run straight into a headwind that cuts through most headbands, and this one kept my forehead warm the whole way without soaking through. The front panel is doing the real work there, not just the wool."
