The Alpinestars GP Plus R V4 Airflow Leather Motorcycle Jacket in Black / White is a performance-focused road jacket for riders who want race-derived leather protection with high levels of warm-weather ventilation. Its close sport fit, pre-curved sleeves and stretch construction are designed to support an active riding position without the bulk of a touring jacket.

Ventilated sport-riding design

Vented shoulders and localised perforation across the chest and sides promote airflow through the jacket. A mesh comfort lining and breathable RIDEKNIT® inner-arm panels help manage heat while retaining the flexibility needed for road and track-inspired riding positions. Alpinestars does not list a waterproof membrane or removable thermal liner for this model, so it is best suited to dry, warmer conditions or use with separate weather layers.

Key features

• 1.3 mm race-grade leather chassis for abrasion resistance and riding comfort
• A-CS® Plus composite stretch panels through the torso for flexibility, breathability and a lower-profile construction

Fit and sizing

This is a close, performance-oriented sport fit. Measure around the fullest part of the chest beneath the armpits, keeping the tape level, and measure the natural waist in line with the navel. Use the measurements below as body measurements rather than garment dimensions. If you intend to use a Tech-Air® system, follow Alpinestars' fitting and compatibility instructions for that system.

For the best result, try the jacket in your normal riding position with the base layers and protection you expect to use. Moto Central can help check sleeve position, armour placement and overall fit in the showroom.
