The Alpinestars KMX-5 v2 Karting Suit maximizes breathability while reducing weight in a package that meets the latest CIK-FIA Level 2 standards. An exclusive outer shell material is combined with a soft knit lining to maximize protection and comfort. Laser cut perforations in the upper chest and back work along with mesh inserts at the sides, crotch and underarms to provide maximum airflow. Ergonomics and mobility are handled by fully-floating shoulders for freedom of movement, and a stretch insert in the lumbar region for a comfortable fit in a seated position.
