The SK-5 is largely based on the GP-5 model, but is specially developed for kart use, with a slightly larger opening aperture as needed in the fierce kart competition. ClC (Complex Laminate Construction) outer shell with a 3 mm thick, 2D visor with F1 aluminium visor system prepared for the use of tear-offs. 4-point upper ventilation system, with large closeable twin intake scoops en closable Double-Delta2 bridged exhaust vent. Comfortable, washable lining material for better ventilation at karting speeds. Extra ridge at the bottom of the shell for more stiffness, removable cheekpads for an even more custom fit. White only.
