ALPINESTARS GP PLUS R V4 AIRFLOW LEATHER JACKET

The Alpinestars GP Plus R v4 Airflow Leather Jacket is a premium sport riding jacket designed for riders seeking maximum ventilation, lightweight performance, and race-inspired protection. Optimized for warm-weather and aggressive riding, this jacket delivers advanced airflow and rider comfort without compromising safety.

Constructed from 1.3mm race-grade leather, the GP Plus R v4 Airflow Jacket offers superior abrasion resistance while maintaining a flexible, comfortable feel. Extensive perforation zones across the chest, sides, and shoulders ensure excellent airflow, keeping the rider cool during high-intensity rides. Vented shoulders further enhance ventilation, making this jacket ideal for warm and hot conditions.

Engineered with a dedicated sport fit, the jacket features pre-curved sleeves and an aggressive cut designed to support a forward-leaning riding posture. Alpinestars’ Nucleon Flex Plus protectors at the shoulders and elbows provide CE-certified impact protection, seamlessly integrated to maintain a low-profile silhouette and unrestricted movement.

A standout feature is the incorporation of Alpinestars Composite Stretch (A-CS® Plus) technology. Strategically placed on the torso, these stretch panels offer exceptional breathability, lightweight construction, and freedom of movement. Compared to traditional leather accordion panels, A-CS® Plus is approximately 9% lighter and offers superior performance, with 30% more elongation, 300% higher tear resistance than HRSF, and 600% greater cut resistance than leather.

Additional technical stretch fabric is applied under the arms, along the inner arms, and around the neck to optimize comfort and fit. These stretch zones work with the jacket’s tailored design to ensure a snug yet flexible fit that moves naturally with the rider.

With its innovative materials, aggressive styling, and high-performance ventilation, the GP Plus R v4 Airflow Jacket is the perfect choice for riders who demand race-grade protection and cooling performance in a sleek, road-ready design.
