ALPINESTARS GP Plus R v4 Rideknit Leather Jacket - Black/White - US 48 / EU 58 3100324-12-58

When you're pushing limits on track or carving canyon roads, your gear needs to match your commitment to performance. The ALPINESTARS GP Plus R v4 combines race-derived materials with engineered comfort, delivering abrasion resistance and impact protection without the weight penalty of traditional leather jackets. This is purpose-built protection that moves with you—not against you.

The GP Plus R v4 integrates Alpinestars' A-CS Plus stretch technology, a hybrid material system that reduces overall jacket weight by 9% while increasing tear resistance by 300% and cut resistance by 600% compared to standard leather. The RIDEKNIT engineered arms provide unrestricted mobility thanks to pre-curved construction and technical stretch panels, while the 1.3mm race-grade leather base maintains the abrasion protection you need when seconds matter. Dual-density DFS shoulder protection and GP Lite elbow armor absorb impact energy without compromising agility, and the jacket is already fitted for Tech-Air 5 and 3 compatible airbag systems.
