Overview & specifications
The GP Plus R v4 Airflow Jacket is engineered and optimized for maximum ventilation and airflow and features extensive race-derived features and materials including a dedicated ‘Sport’ fit with pre-curved arms for maximum riding performance, and race-proven protection on the shoulders and elbows. Vented shoulders and extensive perforation zones on the chest and sides for maximum airflow. Alpinestars composite stretch technology, A-CS® Plus, stretch panels on the torso for exceptional breathability, comfort, and freedom of movement, as well as delivering a lighter weight and a lower profile than a traditional leather accordion panel (the A-CS® Plus panels are about 9% lighter than leather panels). Another key advantage of using A-CS® Plus is its superior stretch performance; A-CS® Plus has about 30% elongation and offers an increase in tear resistance of 300% compared to HRSF (Hyper Resistant Stretch Fiber), and an increase in cut resistance by 600% versus leather. 1.3mm ‘Race’ grade leather construction for the optimum blend of abrasion resistance and comfort. Extensive technical stretch panels under the arms, on the inner arms, and around the neck for an optimized fit.
