The Sparco SJ Pro K-3 redefines what a karting rib protector can be — delivering certified impact protection in a jacket-style design that's far more comfortable to wear than traditional hard-shell vests. Lightweight, breathable fabric keeps you cooler during long sessions, while multi-zone padding guards your ribs, back, and shoulders where it counts most. A full-length zip closure means you're in and out in seconds, not fumbling with straps at the grid. If you've been skipping rib protection because it's uncomfortable, the SJ Pro K-3 fixes that.
