The RST Alpha 5 jeans are an entry-level motorcycle jacket with a CE Certification Rating of A. New and improved with each version of the Alpha (now on to its fifth incarnation!), the Alpha 5 offers CE Level 1 knee protectors, a pocket for hip protectors (sold seperately) and a durable yet lightweight MaxTex construction. They have a fixed mesh lining, fixed waterproof and breathable Sinaqua lining and a removable, midweight thermal lining for comfort in all weather conditions. Adjustability at the waist and legs provides the perfect custom fit. Reflective detailing maximises night visibility, and a 360-degree zip connects to matching RST jackets.
