The race-derived GP Plus V4 sport Leather Jacket is more than just an evolution of the world-renowned V3, its a complete revolution. With a revised silhouette, improved material selection, a new modernized look with refined detailing, and a lighter overall weight, the GP Plus V4 Jacket is the perfect choice. The three main differences new to the GP Plus V4 are the use of A-CS Plus stretch material, GP-R Lite extended elbow armor, and a new, modernized graphic. A-CS Plus stretch material is Alpinestars composite stretch, which is found in the large side panels of the jacket. A MotoGP derived material technology, A-CS Plus stretch provides increased stretch, high abrasion resistance, higher tear resistance than leather, plus a lower profile and overall weight all important features that motorcyclists demand when it comes to increased comfort and performance. Completing the GP Plus V4s chassis construction is a mix of race bovine and regular bovine leather, with tech stretch material on the chest, shoulders, back of the neck, and inner arms. There are DFS Dynamic Friction Shield external shoulder sliders with Nucleon Flex Plus CE Level 1 armor underneath. Internally, the jacket includes a detachable 80g thermal vest and incorporates long direct opening airflow vents on the abdomen for ventilation and climate management.
