Alpinestars GP Tech v4 Leather Suit – Black/Red/Yellow Fluo, US 40 / EU 50, Part 3156822-1355-50

The Alpinestars GP Tech v4 leather suit is designed for professional riders seeking maximum performance, protection, and comfort on the track. Crafted with high-quality kangaroo leather in high-flex zones such as arms, hips, and abdomen, combined with race-grade bovine leather, this suit offers an optimal balance of lightweight construction and durability. The advanced material construction features MATRYX® structural panels on the thigh, chest, back hump, and abdomen, providing excellent ventilation, mechanical resistance, and abrasion protection while maintaining a thin and lightweight profile. These panels are reinforced with Kevlar® to prevent heat transfer and enhance durability, ensuring the rider stays protected and comfortable during intense riding sessions.
The suit incorporates extended Kevlar® stretch paneling around the chest, inner arms, crotch, and back leg to improve flexibility and fit, allowing for natural movement without sacrificing protection. Engineered for an active racing environment, it has a race fit with highly pre-curved arms, knees, and body to optimize aerodynamic performance and reduce fatigue. The GP Tech v4 is also Tech-Air® ready, with an integrated slot on the left forearm designed to accommodate the wireless LED display of the Tech-Air® 10 Airbag System (sold separately), providing additional safety for high-speed riding.
Ventilation and temperature regulation are enhanced with the embedded Cool-iR Tech treatment, which reflects infrared rays from the sun to reduce heat build-up and maintain a comfortable internal temperature. The suit’s strategic perforations on arms and legs facilitate airflow, further contributing to rider comfort during prolonged sessions. The lower leg features MATRYX® material covered with high-performance PU, inspired by MotoGP technology, offering improved ventilation, lighter weight, and greater freedom of movement. The suit also includes a zippered detachable short-leg liner treated with Polygiene® for long-lasting freshness, ensuring comfort even after extended use.
Additional safety features include replaceable elbow sliders, GP DFS armor for impact and abrasion resistance, internal Race-spec GP-R Lite armor for extended coverage, and Bio-Flex Race hip armor for impact protection. The internal paddock’s waist hook system secures the suit in place when off the bike, while the internal design maintains a high level of comfort and protection in key zones. Overall, the Alpinestars GP Tech v4 offers a comprehensive package for professional racers who demand the highest level of active protection, lightweight construction, and advanced ventilation, making it an excellent choice for competitive riding.
