Alpinestars Flex Plus Race leather throughout, race-proven protection on the shoulders and elbows, while delivering optimum levels of rider comfort.

• Flex Plus bovine Race leather construction is 10% lighter than regular bovine leather, while delivering 80% more adaptability for superior freedom of movement, an ultra-adaptive race fit and enhanced abrasion and tear resistance.
• 3D pattern body mapping for an enhanced race fit.
• Dual density DFS RR shoulder and elbow protectors for superior friction control.
• Tech-Air 5 and Tech-Air 3 Ready.
• Hook and loop neck closure with the large built-in flap for a secure closure.
• Ergonomic hook and loop cuffs with a zippered sleeve on the forearm for ease of use.
• Streamlined speed hump for enhanced aerodynamic performance and enhanced ventilation.
• Hump is equipped with a chamber to accommodate hydration pouch.
• Low profile sports collar construction for superior rider comfort and enhanced aerodynamic performance.
• Waterproof inner compartment for the safe and secure storage of valuables.
• Two zippered external side pockets for practical and secure storage.

• GP elbow armour for additional impact protection in a key area.
• Nucleon Flex Plus shoulder armour for superior impact protection.
• Extensive technical stretch panels under the arms, on the inner arms and around the neck for an optimised fit.
• Alpinestars composite stretch technology, A-CS Plus stretch panels on the torso for exceptional breathability, comfort and freedom of movement, as well as delivering a lighter weight and a lower profile than a traditional leather accordion panel (the A-CS Plus panels are about 9% lighter than leather panels). Another key advantage of using A-CS Plus is its superior stretch performance; A-CS Plus has about 30% elongation and offers an increase in tear resistance of 300% compared to HRSF (Hyper Resistant Stretch Fibre), and an increase in cut resistance by 600% versus leather.
• RIDEKNIT engineered inner arms; RIDEKNIT combines high abrasion and tear resistance with high flexibility, comfort and mechanical stretch while still delivering superior comfort and high levels of breathability.
