The Alpinestars GP Tech v4 Leather Suit is a race-focused one-piece motorcycle suit designed for riders who demand advanced protection, lightweight performance, and unrestricted movement on the track. This Black/Red/Yellow Fluo suit is size US 38 / EU 48 and combines kangaroo leather in high-flex areas, including the arms, hips, and abdomen, with race-grade bovine leather for a durable, comfortable construction. The race fit uses highly pre-curved arms, legs, knees, and body positioning to support an aggressive riding posture and precise control.
The GP Tech v4 is Tech-Air® ready and accommodates the Alpinestars Tech-Air® 10 Airbag System with extended hip protection, sold separately. MATRYX® structural panels across the thighs, abdomen, chest, and back hump provide lightweight ventilation, mechanical resistance, and protection against tearing and abrasion. The MATRYX® lower-leg construction is covered with high-performance polyurethane and is derived from MotoGP development for improved airflow, reduced bulk, and enhanced freedom of movement. A dedicated left-forearm slot accommodates the Tech-Air® 10 wireless LED display.
Protection features include GP DFS armor for impact, abrasion, and friction control; replaceable elbow sliders; internal race-spec GP-R Lite armor with extended coverage; and Bio-Flex Race hip armor. Strategic perforations through the arms and legs promote airflow, while the Cool-iR Tech treatment helps reflect infrared solar energy to reduce heat buildup inside the suit. An internal paddock waist hook system helps keep the upper portion secure when off the motorcycle, and the zippered detachable short-leg comfort liner features Polygiene® treatment for long-lasting freshness. Manufactured by Alpinestars, the manufacturer and vendor part number is 3156822-1355-48.
