Underwear is subject to special order conditions and non-returnable due to hygiene.
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. They also carry SFI 3.3 approval for events run to American SFI rules. Our guide on whether fireproof underwear is mandatory covers the rules championship by championship.
What size should I go for?
Sizes run from XS (UK 5-5.5 | EU 38-39) 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.
