The Sparco Prime suit was developed for the McLaren Formula 1 team and is one of the lightest racing suits in the world. The Prime has unparalleled technological features created in the Sparco R&D laboratories. The project involved optimizing every single detail in terms of material and construction. This includes an ultra slim zipper, soft seamless Nomex/Vicosa wrists and ankle cuffs, the neck and shoulder pads were further reduced, thinner thread was used and stitching flattened. It features a 3 layer construction of proprietary Sparco technology. The third outer layer is a double faced mesh made from original DuPont Nomex Comfort woven using Kompact system. The material contains a high percentage of antistatic fibers which provide extremely effective antistatic properties as well as breathability. Prime features pre-curved arms and legs as well as an inner thigh stretch panel for ultimate comfort. FIA 8856-2018 and SFI 3.2A/5 homologated.
