Sparco Rib Vest Pro K3 Kart Racing Rib Protector

The SJ Pro K-3 kart jacket from Sparco combines the impact protection of a chest protector with the comfort and fit of a jacket. The Sparco SJ Pro K-3 kart jacket has been developed as a lightweight and comfortable alternative to the traditional kart rib protector. The material used on the jacket is breathable and anti-bacterial to help prevent perspiration and offers excellent anti abrasion properties. A full-length zip closure makes the kart jacket very easy to put on and take off.

SPARCO RIB VEST PRO K-3 FAQS

What is Sparco Impact Technology?

Sparco Impact Technology combines a 4 mm EPDM layer with 6 mm PU foam to absorb high-energy shocks and vibrations while remaining lightweight and flexible.

What areas does the Pro K3 protect?

The Rib Vest Pro K3 protects the ribs, lower back (via a stretch panel), and shoulders, offering comprehensive coverage in critical zones without interfering with karting ergonomics.

How is the vest comfortable during racing?

Constructed with breathable, antibacterial, abrasion-resistant fabric, it includes a rear stretch panel and a full front zipper for easy on/off and secure fit—designed to reduce fatigue and maintain airflow.

Who is the Pro K3 best for?

This lightweight, low-profile vest is ideal for both indoor and outdoor karting and suits riders seeking minimalist weight with added protection—perfect for recreational and competitive use alike.

Not as High-End as Carbon Models

Good for most racers, but if you want ultra-lightweight and maximum protection, carbon is better.

Absorbs Hits Well

Took a few side impacts, and this really helped reduce rib pain compared to no protection.

Good for Club and Amateur Racers

A solid option for anyone who needs protection but doesn’t want to overspend.

Adjustable and Secure Fit

The straps make it easy to get a tight fit, and it doesn’t shift while racing.

Could Use Better Ventilation

Gets a bit warm during long sessions. More airflow would make a big difference.
