The Sparco Prime suit was developed for the McLaren Formula One 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.
