Racing 4 motorbike leather jacket, an icon of the Dainese collection, with an athletic, close-fitting design that suits a sporty riding style. It is made from fine TUTU cowhide with Nanofeel lining and has four ventilation slits, two on the hips and two on the chest, for maximum thermal comfort. A snug fit and flexibility are ensured by a fit adjustment system at the hips, 2-way stretch S1 fabric panels and Microelastic 2.0 leather inserts on the back and arms. This increases freedom of movement while maintaining the protection typical of leather. The Dainese Racing 4 motorbike jacket has a zip at the hem that allows it to be attached to the motorbike trousers, as well as EN 1621.1-certified protectors made of composite material on the elbows and shoulders, with the latter additionally protected by replaceable external aluminium plates - a special Dainese technology: These support and facilitate sliding in the event of a fall and thus prevent dangerous rollovers on the tarmac.
