The Norrona /29 Warm3 Neck Gaiter is built from Warm3 pile fleece, a heavier-weight fleece that traps warmth without adding bulk. At 54 grams, it layers under a helmet or jacket collar without feeling like one more thing to manage. The regular fit pulls on and off in one motion, so it works as a technical layer on the mountain or an everyday scarf substitute in town. What Our Gearhead(R) Experts Are Saying:"I pull this on before I even get out of the car in the ski lot, and it's still on when I grab coffee on the drive home. The fleece holds enough heat that I don't reach for anything heavier on cold lift days."
