ALPINESTARS GP Plus R v4 Rideknit Leather Jacket - Black/White - US 40 / EU 50 3100324-12-50

If you're serious about track days, road racing, or high-performance riding, your jacket needs to match your commitment to precision and safety. The ALPINESTARS GP Plus R v4 combines race-grade leather protection with engineered comfort features that won't compromise your control or mobility. Built for riders who demand durability without excess bulk, this jacket delivers the protection of a track-focused design with the wearability of everyday gear.

The GP Plus R v4 uses 1.3 mm race-grade leather for genuine abrasion resistance—the kind that matters when contact happens at speed. Dual-density DFS shoulders and GP Lite elbow armor provide layered impact protection without restricting your range of motion, while the pre-curved arms and RIDEKNIT® inner panels keep your positioning natural. A-CS® Plus stretch panels maintain breathability during aggressive riding, and the jacket's 9% weight reduction over traditional leather means less fatigue on longer sessions.
