The Alpinestars KMX-9 v2 S Graph-5 Youth Kart Racing Suit is engineered for young racers, with youth sizing and bold graphics. Featuring a two-layer construction with a tough twill-polymide outer shell for abrasion resistance and a poly-based, moisture wicking technical lining, this suit keeps you dry and comfortable. Mesh panels are integrated into the under-arms and seat area to promote ventilation, while the lumbar stretch panel adds flexibility.
