Alpinestars GP Plus R v4 Airflow Jacket

Fully vented sport leather for hot days

The GP Plus R v4 Airflow is the ventilated version of Alpinestars' GP Plus R v4 sport leather jacket. Vented shoulders and extensive perforation across the chest and sides move the air, while 1.3mm race-grade leather and A-CS Plus composite stretch panels on the torso keep it light and mobile. Nucleon Flex Plus shoulder armour sits under dual-density DFS sliders, with GP Lite armour at the elbows. Certified to EN17092-3 AA class, and Tech-Air 5 and Tech-Air 3 ready.

Sizing and fit

Euro sizing 48 to 60, seven sizes; 50 is roughly a medium, 52 a large and 58 a 3XL. It's a sport fit with pre-curved arms, stretch under and inside the arms and around the neck, a longer back and a 3/4 waist zip for Alpinestars pants. If you'd rather have less airflow, the GP Plus R v4 Rideknit has localised perforation and knitted inner arms.

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 Fibre), 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 optimised fit.
