The OMP One Evo long sleeve top, homologated to FIA 8856-2018. Part number IAA-760-11.
The top of OMP’s underwear range, and the high neck is the point of it: under FIA rules there must be no exposed skin between the layers, and the neck is where people get caught.
What the money buys over the Tecnica
We stock the Tecnica Evo as well and both carry the same FIA homologation, so for scrutineering purposes they are equally valid. This one is lighter, and it uses OMP’s 3D Dry System wicking alongside the 3D cube breathable inserts.
If you race in long stints or in heat, that difference is real. If you do a handful of sprints a year, the Tecnica will not hold you back and we would rather say so.
The part that matters more than the fabric
Fit. Racing underwear works by sitting close to the skin, and a loose top traps air and does less. It should feel snug rather than comfortable when you put it on.

Have you written anything about this exact product?
Yes, we have covered this exact product: The OMP One Evo X Set: Suit, One Evo X Boots And One Evo X Gloves, and OMP One Evo FX Race Boots 2026 – The Latest Evolution in Motorsport Footwear. That is first-hand coverage from our own builds and showroom, not brochure copy.
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 tops 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-S to XXXL. 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.
