Size M Jacket with size M Tech-Air Vest.
The Big Sur is a fully featured touring jacket that is compatible with Alpinestars industry leading motorcycling airbag system, Tech-Air®. Featuring an advanced GORE-TEX® Pro Shell membrane for wind and waterproofing plus high levels of breathability, this jacket when matched with Big Sur GORE-TEX® pants, or any other Alpinestars textile touring pant, offers excellent protection against the weather as well as comfort and protection.
Tech-Air® is the world’s first self-contained street airbag system that independently functions without the need for sensors to be installed on the bike and the subsequent need to link a specific motorcycle to the airbag system used by the rider. This means that Tech-Air® offers the freedom to ride any bike on any surface at any time. Offering instantaneous, high-pressure inflatable protection Tech-Air® gives the rider comprehensive protection in a crash by covering the full back, shoulders, kidney areas and chest. The Tech-Air® street airbag is incorporated into a specially designed vest, which is then attached within and used in conjunction with a compatible jacket. For the initial airbag launch offering there are two jacket models available – the Valparaiso for Tech-Air® touring jacket and the Viper for Tech-Air®street jacket – allowing the Tech-Air® System to be used, interchangeably, in all weather conditions.
