Developed in Alpinestars' state-of-the-art R&D facility, the jersey's multi-layer, low-friction shoulder design helps redirect energy away from the shoulder, enhancing rider safety. Incorporating advanced SX and MXGP race-derived technologies, this jersey offers premium durability, unrestricted movement, and superior ventilation - making it the ultimate choice for championship-level performance.
