The Alpinestars GP Plus V4 Airflow leather motorcycle jacket is Tech-Air compatible. Fully CE-certified riding garment to CE Certified Category II EN 17092-3:2020 Class AA, it features CE Level 1 Category II EN 1621-1:2012 Nucleon Flex Plus shoulder armour and CE Level 1 Category II EN 1621-1:2012 GP-R Lite Elbow armour. It is made from premium Flex Plus bovine leather with vented shoulders and extensive perforation zones on the chest and sides for maximum airflow with Alpinestars Composite Stretch Plus material. The GP Plus v4 Airflow jacket also incorporates Alpinestars Composite Stretch Plus, A-CS Plus, and material on the jacket's side torso and shoulder blades, offering lower weight and increased flexibility and freedom of movement. With A-CS Plus, the stretchability ratio provides 20% additional elongation, and the tear resistance is increased by 300% versus leather. Another benefit of using A-CS Plus is that it offers high breathability with a lower weight and lower profile than leather accordion panelling. The GP Plus v4 jacket has lightweight and breathable perforated Flex Plus race leather for optimal ventilation, especially when the jacket is worn with Tech-Air Airbag Systems like the Tech-Air 10 or Tech-Air 5. The GP Plus v4 is also fully Tech-Air Ready for use with the Tech-Air 5 or Tech-Air 10 Airbag Systems and provides a convenient pocket on the forearm for the Tech-Air 10’s remote LED panel. The GP Plus V4 also has a detachable comfort thermal 80g vest with biostatic Polygiene treatment to keep it feeling and smelling fresh. Available in a choice of colours.
