Construction
• 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).
• 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.
• 1.3mm 'Race' grade leather construction for the optimum blend of abrasion resistance and comfort.
• 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.

Protection
• GP Lite elbow armour for impact protection in a key area.
• Mesh interior comfort liner with pockets to accommodate a back protector or a split chest protector.
• Fully CE-certified riding garment to CE - Category II EN17092-3: 2020 standard - AA Class.
