Sparco RW-11 Seamless Nomex Shirt

The Sparco RW-11 Seamless Nomex Shirt delivers premium fire-resistant protection, exceptional breathability, and lightweight comfort for competitive motorsport drivers. Engineered to meet the FIA 8856-2018 homologation standard, this advanced racing underlayer combines a virtually seamless construction, flexible Nomex-based fabric, and Sparco's innovative X-Cool Silver technology to help drivers stay comfortable and focused behind the wheel.

Designed around the natural seated driving position, the RW-11 racing undershirt offers a close-fitting, compression-style design that moves with the body while reducing pressure points beneath a racing suit. Whether competing in endurance racing, sprint events, or demanding track sessions, the Sparco RW-11 provides the comfort, mobility, and protection drivers need.

Ultra-Lightweight FIA-Approved Racing Underwear with X-Cool Technology

The Sparco RW-11 is engineered for drivers who demand maximum comfort without compromising safety. Its lightweight, breathable construction helps reduce excess bulk beneath a fire-resistant racing suit while providing the thermal protection required for motorsport competition.

Unlike conventional racing underwear with prominent stitched seams, the RW-11 uses an advanced seamless structure to minimize friction and irritation. The stretchable fabric conforms naturally to the driver's torso, allowing unrestricted movement while seated in a racing seat.

Sparco's proprietary X-Cool Silver treatment is designed to promote a cooling sensation by helping draw heat away from the skin. The treatment also provides antibacterial properties to help maintain freshness during extended driving sessions and multi-day race weekends.
