ALPINESTARS GP PLUS V4 SPRINT LEATHER SUIT

The Alpinestars GP Plus v4 Sprint Leather Suit marks a major evolution from its predecessor, the v3, with an all-new construction that integrates advanced materials for superior performance, protection, and rider comfort. Designed for sport and track riders seeking a high-performance, upper mid-level suit, the GP Plus v4 brings together the latest material innovations to offer a premium riding experience.

This next-generation suit is built with Flex Plus race-grade bovine leather—an ultra-flexible leather developed and refined in Italy to offer superior adaptability. With a 6% stretch ratio, Flex Plus leather is 80% more adaptable than traditional bovine leather, allowing the suit to contour naturally to the rider’s body for a perfect fit. This high adaptability translates into enhanced comfort, increased freedom of movement, and improved control on the bike. Despite its flexibility, the Flex Plus leather still meets Alpinestars’ rigorous professional racing standards for abrasion and tear resistance, while also being 10% lighter than standard leather—making it both safer and easier to wear over long sessions.

Complementing the Flex Plus leather is a combination of Alpinestars Composite Stretch Plus material, Matryx® panels for optimized ventilation and weight savings, and HRSF stretch zones for added mobility. Together, these materials ensure a lightweight, breathable, and agile suit that performs under intense conditions.

The suit also features integrated CE-certified GP DFS (Dynamic Friction Shield) external sliders at the shoulders, elbows, and knees for enhanced protection during high-speed slides. Most importantly, the GP Plus v4 is fully compatible with Alpinestars’ Tech-Air® Airbag System, allowing riders to upgrade their safety with world-class electronic impact protection.

With its race-bred design, lightweight construction, and Tech-Air® readiness, the GP Plus v4 Leather Suit is engineered to elevate rider performance without sacrificing safety or comfort.
