The GP Plus R v4 Airflow Jacket is designed 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-tested protection at the shoulders and elbows.

Ventilated shoulders and large perforated areas on the chest and sides for maximum airflow.
Alpinestars' composite stretch technology, A-CS® Plus, features stretch panels on the torso for exceptional breathability, comfort, and freedom of movement, as well as providing a lighter weight and lower profile than a traditional leather accordion panel (A-CS® Plus panels are approximately 9% lighter than leather panels). Another key benefit of using A-CS® Plus is its superior stretch performance; A-CS® Plus has approximately 30% elongation and offers a 300% increase in tear resistance over HRSF (Hyper Resistant Stretch Fiber) and a 600% increase in cut resistance over leather.

1.3mm Race-grade leather construction for the optimal combination of abrasion resistance and comfort.
Extensive technical stretch panels under the arms, on the inside of the arms, and around the collar for an optimized fit.
