The Alpinestars GP Tech v4 Leather Suit is a race-focused motorcycle suit designed for riders who demand advanced protection, lightweight performance, and unrestricted movement on the track. This black and white one-piece suit combines premium kangaroo leather in high-flex areas, including the arms, hips, and abdomen, with race-grade bovine leather for an optimized balance of durability, abrasion resistance, comfort, and weight savings. The engineered race fit uses highly pre-curved arms, knees, and body construction to support an aggressive riding position and precise control.
The GP Tech v4 is Tech-Air ready and can accommodate the Alpinestars Tech-Air 10 Airbag System with extended hip protection, sold separately. A dedicated left forearm slot supports the system’s wireless LED display. MATRYX structural panels on the thighs, abdomen, chest, and back hump provide advanced ventilation and mechanical resistance to tearing and abrasion while remaining thin and lightweight. The lower-leg MATRYX construction is covered with high-performance polyurethane and is derived from MotoGP development, delivering improved airflow, reduced weight, and enhanced freedom of movement. Engineered Cool-iR treatment helps reflect infrared energy from sunlight to reduce heat buildup inside the suit.
Protection and comfort are supported by GP DFS armor, replaceable elbow sliders, internal race-spec GP-R Lite armor, and Bio-Flex Race hip armor. Strategic perforations on the arms and legs improve airflow during demanding riding sessions, while extended stretch panels across the chest, inner arms, crotch, and back of the legs improve flexibility and strength. An internal paddock waist hook system helps keep the suit positioned when walking through the paddock or pit area. The zippered, detachable short-leg comfort liner features Polygiene treatment for long-lasting freshness and convenient maintenance. This Alpinestars GP Tech v4 suit is sized US 42 / EU 52 and carries manufacturer and vendor part number 3156822-12-52.
