The Alpinestars Fusion 1-Piece Suit is engineered for serious track and road-racing applications, combining premium protection with flexible, race-focused performance. This black and white Fusion suit is a US 42 / EU 52 size and features an engineered race fit with highly pre-curved arms, legs, and knees to support an aggressive riding position. Premium bovine racing-grade leather and dual-layer construction in exposed areas provide excellent resistance to abrasion, while strategically placed stretch and ventilation zones help maintain mobility and airflow during demanding rides. The manufacturer and vendor part number is Alpinestars 3153022-12-52.
The suit incorporates RIDEKNIT® seamless stretch panels throughout key mobility areas, including the crotch, rear legs, abdomen, chest, neck, armholes, inner arms, shoulder blades, and calves. Extensive perforation improves ventilation, while dual-layer sections add protection in high-abrasion zones. Innovative MATRYX® structural panels across the thighs, abdomen, chest, and back hump deliver lightweight mechanical resistance against tearing and abrasion with efficient airflow. This configuration is designed to accommodate varied calf shapes and muscle movement while maintaining a secure, performance-oriented fit.
Protection is supported by Alpinestars DFS armor for impact and abrasion resistance with controlled friction management, along with internal race-spec GP-R armor that provides soft comfort and extended coverage in critical zones. Bio-Flex Race hip armor helps protect against impacts, and the suit is Tech-Air® ready for compatibility with the Tech-Air® 5 Airbag System when used with the applicable race algorithm download and system requirements. A knitted collar improves rider comfort, while the zippered detachable comfort liner simplifies cleaning and everyday use. The Fusion suit is a purpose-built choice for riders seeking integrated protection, ventilation, flexibility, and track-ready fitment in a single-piece leather racing suit.
