The Atem V5 Leather Jacket is engineered and optimized for sportsbike and naked sportsbike riders. It features extensive race-derived elements, technology, and materials, including a dedicated ‘Race’ fit with pre-curved arms for maximum riding performance. The jacket is constructed with Alpinestars Flex Plus ‘Race’ leather throughout and offers race-proven protection on the shoulders and elbows, while delivering optimum rider comfort. It incorporates Alpinestars composite stretch technology, A-CS® Plus, stretch panels on the torso for exceptional breathability, comfort, and freedom of movement. A-CS® Plus panels are lighter and offer superior stretch performance with increased tear and cut resistance compared to traditional leather. The Flex Plus bovine ‘Race’ leather construction is lighter than regular bovine leather, providing enhanced adaptability, an ultra-adaptive race fit, and improved abrasion and tear resistance. Additional technical stretch panels are located under the arms, on the inner arms, and around the neck for an optimized fit.
