The Sparco RW-10 Underlayer Shirt is the lightest and most breathable Nomex underwear available, optimized for the ultimate fit and track comfort. Featuring minimal seams, this fire-resistant undershirt is constructed from super-soft, stretchy fabric and sculpted to fit perfectly while in a driving position. It is treated with Sparco's exclusive X-Cool technology, which draws heat away from the skin to cool the driver on the hottest race days. This premium motorsport base layer features a compression-type fit that is perfect for wearing under your racing suit—size up if you prefer a looser fit.
