Our Nomex balaclava is a great head sock for karters and auto racing enthusiasts. Constructed from fire-resistant single layer Nomex for enhanced breathability and comfort, and featuring a reverse stitched design for a closer and less obtrusive fit, our balaclava head sock is a great accessory for individuals who regularly compete with a helmet. Needless to say, if you race karts or are involved in auto racing, we highly recommend our Nomex balaclava head sock - as karters ourselves, we tend to think of balaclavas as one of those "must-have" items.
