The Sparco RW-7 line of undergarments are designed to provide both comfort and protection. The RW-7 is made from a unique mixture of very comfortable soft fibers. The undershirts are made with seamless sides with raglan sleeves to enhance comfort. The RW-7 includes long-sleeved undershirts, long underpants, a balaclava (hood) and mid-calf socks. The balaclavas are one size fits all; undershirts and underpants are available in combination sizes.
Sparco RW-7 undershirts and underpants are designed to fit close to the body due to the soft stretchable fabric. If you prefer a loose-fit please choose one size up. RW-7 shirts and underpants are treated with Sparco’s X-Cool® treatment, which draws heat from the body surface to cool the driver. In addition to cooling the driver, X-Cool® treatment has an anti-bacterial effect.
