Alpinestars GP Plus R V4 Airflow Leather Jacket Black Black

The Alpinestars GP Plus R V4 Airflow is a race-derived sport leather jacket built for hot-weather riding, with vented shoulders and extensive perforation zones across the chest and sides to keep air moving at speed. It is the ventilated take on the GP Plus R V4 chassis, which replaced the long-running V3 with a revised silhouette, refined detailing and a lighter overall build.

Construction is 1.3mm race-grade bovine leather paired with Alpinestars' A-CS® Plus composite stretch panels on the torso, plus technical stretch under the arms, on the inner arms and around the collar. The result is a dedicated sport fit with pre-curved arms that sits naturally in the riding position rather than fighting you on the way to the apex.

Protection is handled by DFS dual-density external shoulder sliders over Nucleon Flex Plus shoulder armour and GP-R Lite elbow armour, and the jacket is Tech-Air® 5 and Tech-Air® 3 ready if you ride with an airbag system. Best suited to track days, fast road riding and summer sport touring.

Wipe the leather clean with a soft, damp cloth after riding; remove insects and road grime promptly so they do not stain or dry onto the hide.
Do not machine wash, tumble dry, bleach or use solvents, petrol-based cleaners or harsh detergents on the leather or the A-CS® Plus stretch panels.
Remove the shoulder and elbow armour and the mesh liner before any spot cleaning, and refit the armour fully seated in its pockets before riding.
If the jacket gets wet, hang it to dry naturally at room temperature away from direct sunlight, heaters and exhausts — forced heat hardens and shrinks leather.
Apply a leather conditioner suited to garment leather occasionally to keep the hide supple; test on a hidden area first and keep conditioner away from the perforated and stretch panels.
Store on a wide-shouldered hanger in a cool, dry, ventilated place rather than folded or compressed in a bag, so the shape and armour positioning are preserved.
Before each ride, check the zips, hook-and-loop cuffs, collar flap and waist adjustment, and keep zips clean and lightly lubricated so they run freely.
Use the 3/4 waist zip to connect the jacket to compatible Alpinestars pants for a secure one-piece feel at track pace.
A back protector is not supplied — fit a compatible CE-certified back protector or chest protector into the liner pockets for full coverage.
If you ride with a Tech-Air® 5 or Tech-Air® 3 system, follow the airbag's own fitment and charging instructions and make sure the jacket is not worn too tight over the inflated airbag's expansion room.
Expect a short break-in period as the race-grade leather moulds to your riding position; retire and replace the jacket after a significant crash or impact, as leather and armour lose protective performance once damaged.
