Revbensskydd Sparco SJ PRO K-3 Svart/Gul Size:130 CO2 smothers the oxygen thatSparco SJ Pro K 3 is a rib vest rib guard for go kart and karting. Mainly suitable for younger drivers as the protective parts are relatively soft and will fold at the large forces that a heavy driver can be exposed to. However, the rib protector can give even a heavier driver a little better comfort, if you get pain or blisters around the ribs and back, this can help but in general we recommend other models if you are not a junior driver.
