The Alpinestars Stella Dyno leather jacket is Alpinestars' modern interpretation of a heritage jacket. It combines premium leather and a regular fit to create a jacket that looks great on and off the bike, in any setting. It also comes with a detachable thermal vest with 80g insulation at the front for effective cold-weather performance. Full CE-Certified A class, it offers Alpinestars Nucleon Flex Plus CE Level 1 shoulder and elbow armour with a pocket for a back protector. Constructed from 1.0-1.2mm 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. The Stella Dyno jacket is also Alpinestars Tech-Air 3 Ready.
