The ZANheadgear® polyester balaclava provides a comfortable layer of protection for your head, neck and face from the elements. 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. Its contoured design mitigates uncomfortable bunching. One size fits most.
