The Balaclava Hinge Polar Fleece Face Mask features the original silicone Airhole which is direct injected onto the fabric, bonding to the front and back to provide a comfortable, hygienic and easy to clean finish. A DWR (durable water repellent) coating to bead water and prevent the fabric from becoming saturated to keep your face dry and comfortable. The Balaclava Hinge allows fabrics with less stretch to function as full head and face protection whilst allowing you to pull the face portion under the chin to free your face and eliminating the need for a beanie.
