The shell openings are then cut using a precision Robotic Hydro-Jet Process. This advanced technical process ensures precise positioning of the visors and ventilation openings as well as perfect edges on all gasket sealing surfaces.

The shell is then finished with 3 layers of fire resistant paint, which includes a primer coat, color coat, and clear coat.

Safety, comfort and durability were main objectives for the internal construction. The Polystyrene inner liner works in conjunction with the outer shell to dissipate the energy created during an impact by absorbing and distributing the shock energy over the largest possible surface. The polystyrene foam inner liner is precisely matched to the shape of the shell. This tight tolerance helps maximize impact management.

Fit and comfort are crucial elements in the function and overall performance of a helmet. Extensive testing on the open cell comfort foam has yielded data allowing us to use the optimum density foam in each area of the helmet. This ensures a proper fitting helmet with maximum comfort. A unique channeling system incorporated into the polystyrene liner allows air to circulate more efficiently throughout the helmet, further enhancing the driver's comfort. The interior is then completely covered in a specially knitted 100% ultra soft Nomex. We have also designed the inner lining of the F1 model to be completely and easily removed, making cleaning and servicing much easier. Special attention has also been paid to all other hardware and accessories. The chinstrap is a fire resistant aramidic fiber with quick pull safety tag. All air ducts, spoilers and stabilizers are as light as possible while still retaining superior strength. Even the visor hardware is made from CNC machined aluminum.

All of this adds up to the finest helmets offered on the market today. No other helmets could have carried the name Sparco.
