This ZANheadgear® SportFlex™ Series Neck Gaiter features a soft yet, durable stretchy shell lined with warm and super soft Cozy Fleece on the inside. We've upgraded and revised the fit of our original Combo Gaiter, with our best selling SportFlex™ fabrication on the outside. This still includes comfort and 50+ UV protection. The Neck Gaiter also sports a contoured cut that fits over your shoulders without bunching and its angled front and back panel allows for extra neck coverage. One size fits most.
