The Sparco RW-11 Seamless Nomex Racing Underwear Bundle combines Sparco's premium seamless underlayers into one complete FIA 8856-2018 approved driver package. This bundle includes the RW-10 seamless balaclava, RW-11 seamless shirt, RW-11 seamless pants, and RW-10 compression Nomex socks.
Designed around the driver's seated position, the RW-11 system focuses on lightweight construction, exceptional breathability, minimal pressure points, and a close compression-style fit. Sparco X-Cool Silver treatment in the shirt and pants helps draw heat away from the body while providing an antibacterial effect for improved comfort during long track sessions.
The Sparco RW-10 Balaclava is designed to provide lightweight FIA-certified protection while reducing common pressure points underneath a racing helmet. Its seamless construction eliminates seams across the mouth and chin, while the traditional center seam across the forehead has also been removed.
The Sparco RW-11 Shirt combines a fully seamless structure with ultra-soft stretchable material for a close, comfortable fit beneath a racing suit. Its compression-style construction minimizes excess material while maintaining excellent freedom of movement.
Sparco X-Cool Silver treatment helps draw heat away from the driver's body while providing an antibacterial effect for improved comfort and freshness during long sessions.
The Sparco RW-11 Pants use the same seamless, stretchable construction and X-Cool Silver treatment as the matching shirt. Their close compression fit helps reduce bunching and excess material underneath a racing suit while maintaining excellent mobility in the cockpit.
The Sparco RW-10 Compression Socks use a unique helical structure that provides graduated Class 1 compression. Maximum pressure is applied around the ankle and gradually decreases toward the calf to help support the upward return of blood circulation.
This graduated compression design is intended to help reduce muscle fatigue, improve comfort, and support driver focus during long racing sessions.
The RW-11 shirt and pants use Sparco racing underlayer sizing. Because these garments are designed with a compression-style fit, drivers who prefer a looser fit should consider selecting one size larger than normal.

The Sparco RW-11 system is designed for drivers who want premium FIA-certified protection with minimal bulk, advanced cooling technology, and a close performance fit. The combination of seamless construction, X-Cool Silver treatment, and RW-10 graduated compression socks makes this package especially well suited for endurance racing, competitive motorsport, and drivers who spend extended periods in the car.
