Sparco SJ Pro K-3 Rib Protector Vest
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.

Most karters know they should be wearing a rib protector. Fewer actually do — because the traditional hard-shell vest is bulky, stiff, and fights you every time you try to get low in the seat. Sparco designed the SJ Pro K-3 to eliminate every one of those excuses.
Built in a jacket-style form factor, the SJ Pro K-3 wraps protection around three of the most vulnerable areas in karting: the ribs, back, and shoulders. Twelve millimeters of vibration- and shock-absorbing foam at the ribs handles the constant chassis feedback and lateral impacts that make long race days brutal on your body. A low-profile 4mm back panel keeps your seating position natural and uncompromised, while 6mm shoulder padding extends into the collarbone zone — coverage that traditional vests rarely offer.
The outer shell uses a breathable, anti-bacterial fabric that actively works against sweat buildup, keeping you more comfortable and focused from practice to the final. A rear stretch panel accommodates the bent, tucked position of an aggressive kart seating position without pulling or binding. The full-length zip closure makes suiting up and stripping off between sessions fast and hassle-free.
Available in youth and adult sizing across two colorways, the SJ Pro K-3 is the kind of gear you'll actually remember to put on — because it doesn't feel like a chore.
