The Sparco Rib Pro K-4 adds protection and padding without bulk, through the use of Sparco Impact Technology, a 4mm thick EPDM material mated to a 6mm PU foam. This combination equally protects against high-energy impacts and provides vibration dampening. A thermoplastic shell is then applied to this material to provide increased impact protection. Special cutouts greatly help increase breathability, while rubber edging on the shell helps reduce wear against the kart suit. A simple tape adjustment system makes putting on or taking off the protector a breeze.
