The 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 socks. The hoods are one size fits all; undershirts and underpants are available in combination sizes. The 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. Socks are available in sizes from 38/39 to 46. 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, the X-Cool treatment has an anti-bacterial effect. The RW-7 line is FIA 8856-2018 approved.

Do I actually need FIA underwear?
If your championship requires it, this is the layer scrutineers ask about, and it is strongly recommended under any suit regardless. These socks are homologated to FIA 8856-2018, the current FIA standard, so the label is there when scrutineers ask for it. Our guide on whether fireproof underwear is mandatory covers the rules championship by championship.
What size should I go for?
Sizes run from XS to XL. Underwear layers should sit close to the skin without pinching, as loose fabric wrinkles under the suit and gets uncomfortable fast. Between sizes, take the smaller one for a base layer.
How do I wash it?
Underwear layers are the one bit of racewear you should wash after every use: cool and gentle, no bleach or fabric softener, air dry. That keeps the suit itself needing far fewer washes. Full routine in our racewear care guide.
