The Alpinestars GP Plus v4: an upper mid-level race leather suit for sport and track riders, with stretch leather, race armor and Tech-Air compatibility.
What the features mean on the road
- Flex Plus race bovine leather, tanned in Italy: Alpinestars says it flexes 80% more than regular bovine leather and is 10% lighter. Why it matters: a suit that moves with you in the tuck.
- Meets Alpinestars' professional racing standard for abrasion and tear resistance.
- A-CS Plus stretch panels and Matryx ventilation panels: lower weight and better airflow, even with an airbag.
- Perforated chest, abdomen and thighs.
- GP DFS shoulder, elbow and knee sliders.
- GP-R elbow, forearm, knee and shin armor, Nucleon Race shoulders.
- Detachable Polygiene comfort liner: treated to stay fresher.
- Tech-Air ready: built to accept Alpinestars' Tech-Air system (airbag sold separately). Works with Tech-Air 5 or 10; a forearm pocket holds the Tech-Air 10 LED panel.
