The Sparco X-Cool Socks are part of the Sparco Shield RW-9 line of Nomex® undergarments that 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. Sparco 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 Sparco 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 Sparco Shield RW-9 collection has pieces to fit every driver’s style, including short-sleeved t-shirts, 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 Sparco Shield RW-9 line is FIA 8856-2000 rated (EXCEPT SHORT-SLEEVED T-SHIRT).
