Certified to FIA and SFI homologation standards, the GP Pro Comp suit has a three-layer construction offering ultimate protection and lightweight construction, while the breathable lining aids driver comfort. Pre-curved arms and legs and stretch panels on the crotch, waist and underarm offer optimum levels of movement and comfort, while the cuffs on the arms keep everything in place and prevent the material from bunching up. Other thoughtful details include a soft, ribbed knit collar and flat seams on the shoulders.
