What Our Gearhead(R) Experts Are Saying: "This headband is the one I reach for when ski touring or trail running in cooler temps. It stays in place under a helmet, regulates heat incredibly well, and doesn't soak out like cotton or synthetic bands."We reach for the Fleece Light Headband when our mission demands lightweight warmth without sacrificing breathability. Ortovox blends fine Tasmanian merino wool with polyester and elastane for a fit that stays put and a feel that stays dry, even when we're charging uphill on high-output days. This slim, performance-driven headband insulates effectively while releasing excess heat and moisture.
