The OMP Tecnica Evo long sleeve top, homologated to FIA 8856-2018. Part number IAA-774-9.
The Evo version of the Tecnica top, which carries part number IAA-774. Both are FIA 8856-2018 and both satisfy the regulations, so if you are choosing between them, ask us and we will tell you what actually differs.
Knitted without seams, and that is the useful bit
Knitting it in one piece means no pressure points, which sounds like marketing until you have worn a seamed top under a harness for an hour. The strap runs over your collarbone and anything raised underneath it becomes a sore spot you cannot do anything about mid stint.
The 3D cube inserts sit over the areas that actually sweat and are there to move heat out rather than to look technical.
Nomex
Flame retardant by fibre rather than by treatment, which is why it does not wash out over the life of the garment the way a treated fabric can.
It should fit snugly. Tell us your chest measurement and your suit size.
Have you written anything about this exact product?
Yes, we have covered this exact product: The OMP Tecnica Evo Set: Suit, Tecnica Race Boots And Tecnica Race Gloves, and OMP Tecnica Evo 2026: Lighter Underwear, And A Size Chart That Changed. 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 XXL. 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.
