The Blacktrack Leather Jacket is Alpinestars modern interpretation of the classic biker jacket, and combines premium leather and a tailored fit to create a jacket that looks great, on and off the bike, in any setting. This jacket is also equipped with a detachable thermal vest, which adds to its performance and versatility. Constructed from 1.0 - 1.2 mm bovine leather for the optimum blend of light weight, thinness, suppleness, and abrasion resistance. The leather is dip dyed, and the oils used during this process results in a more natural finish with superior overall softness and a softer feeling against the skin. Detachable thermal vest with 80-gram insulation at the front for effective cold weather performance. Integrated metallic gunmetal zip and metallic shoulder badge and trim for a premium finish. Leather accordion panels on the shoulder blades for an enhanced rider fit and optimum freedom of movement.
