Alpinestars GP Plus v4 Leather Suit – Black/White US 42 / EU 52 – Part 31505231252

The Alpinestars GP Plus v4 Leather Suit is a significant upgrade over the previous v3 model, featuring an innovative construction that combines high-performance materials for optimal comfort, protection, and flexibility. Crafted from specially tanned Flex Plus racing bovine leather, this suit offers an exceptional 6% adaptability ratio, which is 80% more flexible than standard bovine leather, providing a close, personalized fit and enhanced freedom of movement. The leather is also 10% lighter, reducing rider fatigue during long sessions or races. The suit’s strategic perforations across the chest, abdomen, and thighs ensure excellent airflow, keeping the rider cool even during intense riding conditions. Perforation combined with lightweight, breathable Matryx® panels on the torso delivers superior ventilation, especially when used with Alpinestars' Tech-Air® airbag systems like the Tech-Air® 10 or 5, making it ideal for both sport and track riding scenarios. The incorporation of Alpinestars Composite Stretch Plus and A-CS® Plus materials on the side torso and shoulder blades reduces weight while increasing flexibility and durability, supporting the suit’s high-performance demands. Features such as HRSF stretch inserts in the crotch, legs, and inner arms further enhance comfort and mobility, allowing for natural movements and reduced fatigue over extended use. For protection, the GP Plus v4 includes GP-R armor on elbows, forearms, knees, and shins, along with Nucleon Race shoulder armor, offering impact absorption and abrasion resistance. The suit’s design also emphasizes convenience with soft stretch wrist and ankle cuffs, a removable Polygiene®-treated liner to keep the interior fresh, and a dedicated pocket for the Tech-Air® 10 remote LED on the forearm. Fully compatible with Tech-Air® airbag systems, the GP Plus v4 provides advanced safety features essential for high-speed riding and racing, making it a versatile choice for serious riders seeking cutting-edge protection and comfort.
