Alpinestars - GP Plus R V4 Rideknit Leather Jacket

This isn’t just a jacket—it’s armor disguised as style, built for riders who thrive on adrenaline and demand pro-level performance. The GP Plus R v4 Rideknit Leather Jacket is made from 1.3mm race-grade leather that laughs at abrasion and shrugs off the asphalt, all while staying flexible enough to move with you at full lean.

Tech-Air® airbag system compatibility takes safety to another level, while dual-density DFS shoulder sliders and GP Lite elbow armor keep you protected in the hot zones. The Rideknit® engineered inner arms and Alpinestars’ A-CS® Plus stretch panels keep airflow high and restriction low, so you stay cool and agile whether you’re carving canyons or hammering laps.

CE-certified to AA class standards, this jacket fuses race-bred protection with everyday ride comfort. It’s sharp, aggressive, and unapologetically built for speed—because when you’re chasing limits, the last thing you need is gear that holds you back.

Key Features:

• GP Plus R v4 RIDEKNIT® Leather Jacket is optimized for superior freedom of movement and rider comfort, and features extensive race-derived features and materials including a dedicated ‘Sport’ fit with pre-curved arms for maximum riding performance, and race-proven protection on shoulders and elbows
• Alpinestars composite stretch technology, A-CS® Plus, stretch panels on the torso for exceptional breathability, comfort, and freedom of movement, as well as delivering a lighter weight and a lower profile than a traditional leather accordion panel (the A-CS® Plus panels are about nine percent lighter than leather panels). Another key advantage of using A-CS® Plus is its superior stretch performance; A-CS® Plus has about 30% elongation, and offers an increase in tear resistance of 300% compared to HRSF (Hyper Resistant Stretch Fiber), and an increase in cut resistance by 600% versus leather

• RIDEKNIT® engineered inner arms; RIDEKNIT® combines high abrasion and tear resistance with high flexibility, comfort and mechanical stretch while still delivering superior comfort and high levels of breathability
