This protective jacket has been designed for both outdoor and indoor use, for the non-professional pilot who wants to ensure high shock absorption and anti-vibration performance without sacrificing comfort and lightness. The outer fabric is characterized by a great breathability combined with excellent resistance to abrasion and tearing. It is also breathable and antibacterial to ensure maximum comfort even during the most intense driving sessions. The padding on the back is preformed and the grooves have been specially developed to facilitate the pilot while driving. SJ PRO K-3 has been developed for both outdoor and indoor riders, with a very wide range of sizes necessary to cover the needs of the child pilot as those of the adult pilot. The frontal zip closure allows the pilot to wear the jacket quickly.
