Sparco RW-4 MY22 Roll-Neck Underwear Top Black (FIA)
The Sparco RW-4 MY22 Roll-Neck Underwear Top is a homologated base layer for adult drivers competing in rally and circuit events where FIA-certified fireproof underwear is required by the regulations.
The garment is made from aramid fabric, which provides genuine flame resistance while remaining soft against the skin. Its relaxed cut follows the body without restricting movement in the cockpit. The roll-neck collar sits close to the throat, forming a continuous protective barrier between the top and a balaclava or helmet edge. Full-length sleeves extend to the wrists, ensuring complete coverage of the arms and forearms. A sewn-in compliance label confirms the FIA Standard 8856-2018 certification.
Finished in plain black with no contrasting inserts or prints on the body, the RW-4 MY22 layers discreetly under any race suit colour and satisfies the current FIA 8856-2018 standard for sanctioned motorsport competition.
