Ergodyne - EGO16955 N-Ferno 6955 Insulated Balaclava Face Mask features three layers for maximum protection in extreme cold. Lining is made of Polartec Power Grid fleece - a moisture-wicking, grid-construction fabric that delivers enhanced warming while remaining breathable and lightweight. Stretchable, polyester-spandex exterior allows a comfortable fit on a variety of head sizes. Front, ribbed panel features an insulated mid-layer for additional warmth where it's needed most. Ribbed design of the three-layer front panel provides a loft that creates a gap between the material and mouth, allowing easier breathability than some single-layer options. Reflective accents enhance visibility at night or in low-light conditions. Wear this balaclava as a full face mask, neck gaiter or face shield. Unique, hinged design allows you to adjust the amount of coverage you need depending on the weather. Angled bottom minimizes bulk while layering. Balaclava fits under hard hats, ski helmets and other head protection.
