The Sparco SJ Pro K-3 Karting Vest introduces a new lightweight method of providing torso protection for both indoor and outdoor kart racing. Optimized for the recreational karter, but perfectly suitable as a minimalist protector for the pros, the SJ Pro K-3 features pre-curved and ergonomically situated padding throughout the back and sides. The padding is constructed using Sparco Impact Technology, a 4mm thick EPDM material mated to a 6mm PU foam, to equally protect against high-energy impacts and providing vibration dampening. Easy to put on and take off, the highly breathable abrasion resistant cloth vest closes with a full front zipper.
