Race-inspired ventilation meets everyday riding performance
Price ~€300
The Alpinestars T-GP Plus R V4 Airflow review has been one of the most requested on Gear4Moto since we launched our jackets category. Alpinestars is one of the most respected names in motorcycle protection, and the T-GP Plus R V4 Airflow is their answer to the question every sport rider asks in summer: how do you stay cool without giving up protection? After extensive research and long-term tester feedback from Motorcycle Gear Hub, who owned the jacket for almost a year, we have a clear picture of where it excels and where it falls short.

Alpinestars T-GP Plus R V4 Airflow review: In-depth analysis
The Alpinestars T-GP Plus R V4 Airflow is engineered for maximum ventilation from the ground up. The construction combines 450D poly-fabric with 600D reinforcements at critical impact zones, extensive mesh panels across the chest and back, and strategically positioned perforations on the chest, back yoke, and forearms. The result, according to Motorcycle Gear Hub who tested the jacket across almost a year of riding, is a jacket that delivers genuinely superior airflow compared to alternatives in the same price bracket. For riders in warm climates or anyone who spends time in stop-start summer traffic, the ventilation performance is one of the strongest arguments for this jacket.
The sport fit is tailored and purposeful. Pre-curved arms reduce arm fatigue in the riding position and prevent material bunching at the elbows, which is a consistent irritation in jackets designed around a more upright cut. Ergonomic stretch inserts under the arms and on the inner arms improve freedom of movement without compromising the structure of the jacket. Riders frequently praise the comfort in the riding position specifically, with multiple RevZilla reviewers noting it feels significantly more natural on a sportsbike or naked bike than competing jackets at the same price.
The protection system is functional but not exceptional. Nucleon Flex Plus shoulder and elbow protectors provide CE-certified impact absorption, and additional DFS Lite shoulder protectors add friction control at the outer shoulder – a detail more commonly found on higher-priced jackets. However, motorcyclegear.com noted that the CE Class A abrasion rating is a disappointment at this price point, given that both Klim and REV’IT offer mesh jackets in the same price range that achieve the higher AA rating. For riders who prioritise maximum abrasion protection, this is a genuine limitation worth considering before purchasing.
The Tech-Air compatibility is a meaningful future-proofing feature. Both the Tech-Air 3 and Tech-Air 5 airbag systems can be integrated into this jacket, which means riders who invest in Alpinestars’ airbag technology later do not need to replace their jacket. This is a level of system planning that adds long-term value even for riders who are not currently using an airbag vest.
Sizing is the most consistent complaint across all sources. RevZilla reviewers widely report the jacket runs small, particularly across the chest and shoulders, and the general recommendation is to size up from your usual jacket size. Motorcycle Gear Puzzle confirmed the European sport fit works well for average or trim builds but is a harder fit for broader or stocky riders. Checking the Alpinestars size guide carefully and ordering from a retailer with a clear returns policy is strongly advised.
The zipper durability issue flagged by some long-term users is worth monitoring. It appears to affect a minority of jackets and may relate to usage patterns, but it is a legitimate quality concern at this price point that has been reported across multiple independent sources.
V4 Airflow vs V4 Rideknit:
Alpinestars offers two versions of the GP Plus R V4. The Airflow uses High Resistant Stretch Fabric (HRSF) for the stretch panels. The Rideknit version upgrades those panels to Alpinestars’ proprietary Rideknit fabric, which Motorcycle Gear Hub confirmed is a step up in comfort, compliance and ventilation. The Rideknit costs approximately €100 more. For most riders the Airflow delivers excellent value. For riders who spend long hours in the saddle and want the best possible comfort, the Rideknit is worth the additional investment.

GEAR4MOTO VERDICT
The Alpinestars T-GP Plus R V4 Airflow delivers exceptional ventilation in a sport-focused package that suits riders who spend time on sportsbikes or naked bikes in warm conditions. The pre-curved arms, ergonomic stretch panels, and extensive mesh construction make it one of the most comfortable summer sport jackets in its price bracket. The CE Class A rating rather than AA is a genuine limitation compared to some competitors, and the sizing runs small enough to require careful attention before ordering. For riders in warm climates who want an Alpinestars jacket at an accessible price, the V4 Airflow is a strong choice. Riders who want maximum abrasion protection should consider the REV’IT Eclipse 2 or upgrade to the V4 Rideknit.
