The ZANheadgear® Polyester Balaclava offers optimal protection from the elements by providing coverage of the head, neck and face. Constructed of 100% stretchy polyester, this balaclava allows for snug, yet comfortable fit. It also features two smooth seams that are strategically placed to eliminate an irritating pressure point that a center seam may cause when worn under a helmet. The ZANheadgear® Polyester Balaclava also boasts vibrant graphics and its contoured design mitigates uncomfortable bunching. Electric Skull Design.
