The Prime LT is a limited edition suit available only for the US market. The Prime LT features an all-new design in two colorways. This is a limited edition suit, only available for 2021 (while supplies last). The Prime LT is the same suit material developed for the Mclaren F1 team and is one of the lightest FIA approved racing suit in the world.

The Prime LT 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 the stitching flattened even more. The Prime LT 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 the Kompact system. The material contains a high percentage of antistatic fibers which provide extremely effective antistatic properties as well as breathability. The suit weighs from 240 to 270 gr per square meter (depending on size).
