The Tech-Air® Ready GP Plus v4 Leather Suit represents a complete revolution in performance riding gear, featuring an all-new construction designed for sport and track riders who demand the latest material innovations. This upper mid-level suit utilizes ultra-flexible Flex Plus race bovine leather, specially tanned and refined in Italy. This premium leather is highly adaptive to the body, supporting a 6% adaptability ratio—80% more than regular bovine leather—resulting in unrivalled comfort, feel, and a precise fitment while remaining 10% lighter than standard hides.
For enhanced flexibility and freedom of movement, the suit incorporates Alpinestars Composite Stretch Plus (A-CS® Plus) on the side torso and shoulder blades. This advanced material provides 20% additional elongation and increases tear resistance by 300% compared to traditional leather. To ensure optimal thermal management, strategically placed lightweight and breathable Matryx® material panels are located on the torso, complemented by extensive perforations on the upper chest, abdomen, and thighs. This ventilation system is especially effective when the suit is worn with integrated airbag systems.
Protection is paramount, with the GP Plus v4 featuring race-proven GP-R elbow, forearm, knee, and shin armor, along with Nucleon Race shoulder armor. The suit is equipped with GP DFS shoulder, elbow, and knee sliders for superior abrasion resistance. For those seeking the ultimate in rider safety, the suit is fully Tech-Air® Ready, compatible with Tech-Air® 5 or Tech-Air® 10 Airbag Systems, and includes a convenient forearm pocket for a remote LED panel.
Additional technical features include:
- HRSF stretch inserts in the crotch, back of legs, inner arms, and pectoral areas for an optimized riding fit.
- Soft stretch wrist and ankle cuffs for enhanced rider comfort.
- A detachable comfort liner featuring biostatic Polygiene® treatment to keep the suit feeling and smelling fresh.
- Professional racing standard abrasion and tear resistance across all primary construction zones.
