The Viper Air V4 remains a versatile, summer vented motorcycle jacket in its fourth iteration. Flexible, with plenty of adjustability, it adapts to the conditions like a true adder would.
The Viper Air V4 is a vented jacket with a removable windbreaker liner. This liner – essentially – transforms the jacket from a vented summer motorcycle jacket into a ‘regular’ motorcycle jacket suitable for mid-season rides. The only thing missing is a waterproof feature, but then again, a separate rain jacket is always an option. For the summer motorcycling enthusiast, this is certainly a top contender!
The Viper Air V4 is a highly versatile jacket. Equipped with mesh panels on the arms, chest, and back, it’s paired with a ‘chassis’ made from a mix of wear and tear-resistant (600D) materials, forming a reliable base. And there’s not much more you need beyond that.
Reflective details and pre-curved anatomy are standard, as expected from a top brand like Alpinestars. The windbreaker liner can be quickly inserted or removed, dramatically increasing the Viper Air V4 motorcycle jacket's usability across a wider range of temperatures. Strategically placed large tech-mesh panels ensure optimal airflow.
Alpinestars, staying true to its name and reputation, ensures excellent impact protection. While a Nucleon Flex Pro Ci chest protection and a Nucleon Plasma Level 2 back protector or Nucleon KR-CELLi Level 1 back protector are optional, the Level 1 Nucleon Flex Plus shoulder and elbow protectors provide a solid foundation. Additionally, the Viper Air V4 motorcycle jacket is Tech-Air® compatible, meaning it’s ready to be used with the Tech-Air® Airbag System.
With pre-curved sleeves to reduce fatigue, a water-resistant inner pocket, two zippered front pockets, a low collar for added comfort around the neck, and belt loops, this motorcycle jacket is a true reflection of vintage Alpinestars quality and design.
