Sparco Victory RS-7 suit is the only single layer suit to achieve a SFI 3.2A/5 rating. Sparco uses HOCOTEX® technology which allows a single layer suit the same amount of protection that has been previously achieved using multi-layer fabric. HOCOTEX® creates a honeycomb structure with internal air cells that ensure the driver even more fire protection. The RS-7 is twice as breathable compared to a suit produced using traditional technology. Ultimate flexibility has been achieved with the use of this relatively thinner fabric. The Victory RS-7 also features 360 degree stretch arm gussets that provide more mobility in a seated driving position.
