This latest balaclava from Sparco is manufactured from a revolutionary new material called Shield RW-9 for the very best in fit and comfort. It is designed to adhere, as much as possible, to the drivers body shape without creating friction between the garment and skin. Shield RW-9 is as seamless as possible and features two different fabrics, matched together to ensure maximum breathability in key areas. Weighing just 180 g/m2, it is one of the lightest fireproof underwear material in the world and has the added benefit of Sparco's X-Cool silver treatment which is antibacterial and gives a sensation of freshness. FIA 8856-2000 and SFI 3.3 Level 5 approved.
