The youth-sized Alpinestars KMX-3 v2 S Karting Suit is designed for budget minded pros looking for excellent fit and performance. The advanced 2-layer construction offers CIK-FIA homologated protection together with a stretch nylon outer fabric for vastly improved fit and performance. Mesh panels are placed throughout for unparalled breathability, while a soft poly-toweling inner layer excels at wicking moisture away from the skin. Full floating arms are combined with ergonomically placed arm, leg and torso paneling for the perfect fit while seated on track!
