Race-Grade Performance with Advanced Material Innovation

The Alpinestars GP Plus V4 Sprint One Piece Leather Suit is a lightweight, high-performance garment engineered for riders who demand race-proven protection and adaptability. Constructed from premium Flex Plus bovine leather and reinforced with Alpinestars Composite Stretch technology, this suit delivers exceptional abrasion resistance while maintaining a supple, flexible fit. It is fully Tech-Air ready, designed to integrate seamlessly with the Tech-Air 7x or Tech-Air 10 Airbag Systems for maximum track-side safety.

Key Features

• Flex Plus Leather: Dual-layer premium bovine leather in high-impact zones for enhanced durability and superior abrasion resistance.
• A-CS Technology: Advanced composite stretch back panels provide 30% more elongation and significantly higher tear and cut resistance than traditional leather.
• Optimised Ventilation: Fully perforated leather panels throughout the chassis ensure maximum airflow and cooling during high-intensity riding.
• Race-Spec Aerodynamics: Features the Supertech R10 aero hump, specifically profiled to work with the Supertech R10 helmet for streamlined performance.
• Comprehensive GP-R Armour: Race-derived protection on the elbows, knees, and shins provides extended coverage and impact absorption.
• DFS Friction Control: External Dynamic Friction Shield sliders on the shoulders and knees, including removable elbow sliders, manage heat and friction during slides.
• Matryx Shin Panels: Engineered material on the lower leg offers a high resistance-to-weight ratio with increased breathability and flexibility.
• Pre-Curved Race Fit: Highly articulated body, arms, and knees reduce rider fatigue and improve comfort in a full racing tuck.

Advanced Materials and Construction

The GP Plus V4 Sprint utilises a sophisticated blend of materials to balance weight and safety. Aramid reinforcements are strategically placed at the elbow flexion zones to provide additional strength in critical areas, while Hyper Resistant Stretch Fabric (HRSF) ensures the rider retains full freedom of movement without compromising on tear resistance. This construction ensures the suit remains lightweight and adaptive, conforming to the rider's movements on the bike while maintaining its structural integrity under extreme stress.
