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 8856-2000, the previous FIA standard. Many championships still accept it, but check your regulations before buying for competition. Our guide on whether fireproof underwear is mandatory covers the rules championship by championship.
What size should I go for?
Sizes run from S (UK 5-6 | EU 38-40) to XL (UK 11-12 | EU 46-47). 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.
