Alpinestars - Supertech LE Hay Jersey, Pant Combo




Alpinestars - Supertech LE Hay Jersey
The Supertech Hay Jersey is engineered for elite-level motocross riders seeking exceptional dirt riding performance. At its core, Alpinestars' innovative AFD (Alpinestars Force Deflection) shoulder technology helps minimize shoulder injury risk by deflecting impact forces and reducing rotational acceleration during crashes or contact with the ground. 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.
Key Features:
- Innovative Supertech AFD Shoulder Construction: Race-proven, multi-layer, low-friction design reduces impact force and rotational stress to the shoulder, minimizing the risk of injuries. Seamlessly integrated into the jersey’s construction, AFD enables sliding and rotational movement to deflect force, reducing oblique and rotational stress on the shoulder during crashes or contact with the ground.
- Athletic Pro Racing Fit: Ultra-light, ergonomic cut for maximum mobility on the track.
- Professional Racing Performance: Designed for competitive riding, delivering top-level flexibility, comfort, and fit.
Construction:
- Lightweight, multi-layer Supertech AFD shoulders for optimal energy deflection.
- Advanced stretch mesh construction with localize perforations for ultra-lightweight, breathability, and maximum ventilation.
- Extensive, strategically positioned laser-cut perforations throughout the upper and lower arms, sides, and armpit areas for additional airflow and ventilation.
- Innovative Stretchnet construction incorporates fully elastic material on the back, ensuring superior flexibility and airflow.
- Seamless design (eliminating side, elbow, and underarm seams) for enhanced rider comfort.
- Extended rear for greater coverage and compatibility with Alpinestars MX pants.
- Flat stretch construction on the arms with slight curvature at the shoulders for enhanced range of motion.
Protection:
- Alpinestars’ innovative Supertech AFD technology helps minimize force transmission to the shoulders, reducing the risk of injury.
