These latest underwear long johns from Sparco are manufactured from a revolutionary new material called Shield RW-9 for the very best in fit and comfort
Shield RW-9 is a new material from Sparco and 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.
The labels have been deleted to guarantee maximum comfort and the information is now printed direct onto the garment. Weighing just 180 g/m2, Shield RW-9 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.
