The RW-4 NON-FIA/SFI line is ideal for track days if you’re searching for underwear that keeps you comfy and adds an additional layer of protection. The sole distinction between these underwear and our homologated RW-4 counterparts is their configuration; both are made of the same premium material. The NON-FIA/SFI RW-4 undergarments are a great choice for drivers who aren’t competing professionally but yet wish to be safe on the track because the FIA and SFI don’t accept single-layer balaclavas, boxer short lowers, or short-sleeved shirts.
- Soft and comfortable feel
Sparco T-shirt (without FIA homologation) has short sleeves and a soft fabric for added comfort.
– Low Neck T-Shirt
– Half Sleeves
– Soft-Touch Interlock Construction
– Not FIA Approved
