JUNEAU Neck Gaiter. Designed and built for cold climates. Replacing the Herning series with a new and more dynamic fabric, you will receive the same warmth, moisture management and reliability that has made the product great over the last 30 years. The Juneau fabric moves with your body, but is not restrictive. These garments work best as part of a Helly Hansen 3 Layer System. Trust Helly Hansen to keep you warm in any weather.
