The Shield RW-9 line of Nomex® undergarments provides the highest level of breathability, comfort and protection. When designing this line, Sparco studied the driver’s sitting position to ensure ultimate fit and comfort. Shield RW-9 uses a seamless construction with ultra-soft stretchable material. Three are two different woven materials in key areas; thin stretch Nomex® for comfort and mobility as well as a double perforated Nomex® for increased breathability and ultimate comfort. The minimal seams are stitched flat with thin specialized thread for added comfort. All Shield RW-9 pieces are treated with Sparco X-Cool Silver which draws heat from the body surface to cool the driver. In addition to cooling the driver, X-Cool Silver treatment has an anti-bacterial effect.  

The Shield RW-9 collection has pieces to fit every driver’s style, including short-sleeved undershirts, long-sleeved undershirts, long underpants, a balaclava hood with a single eye opening, knee-length socks and mid-calf socks. Available in black or white in four sizes XS/S, M/L, XL/XXL, XXXL for guaranteed fitment; socks are available in sizes from 38/39 to 46. The Shield RW-9 line is FIA 8856-2000 rated (EXCEPT SHORT-SLEEVED UNDERSHIRT). 

* SHIELD RW-9 short-sleeved undershirts are NOT FIA APPROVED.

The RW-9 Compression sock is the only FIA approved compression sock on the market. It uses a seamless construction that delivers Class 1 compression force. This graduate compression force uses the same principles used in action sports. The RW-9 sock exerts maximum pressure at the ankle and then decreases going upwards towards the calf, to facilitate the upward return of blood circulation. This compression force is proven to minimize muscle fatigue to improve driver comfort and focus.  Available in black or white
