The Alpinestars Tech-Air® 3 V2 System represents the pinnacle of autonomous motorcycle airbag technology, engineered for riders who demand uncompromising protection without sacrificing comfort or versatility. As Alpinestars' lightest self-contained airbag system, it's purpose-built for road riding, touring, daily commuting, and light adventure use, delivering race-proven safety technology to every journey.
Designed with real-world versatility in mind, the Tech-Air® 3 V2 can be worn discreetly under your existing jacket or over the top for maximum visibility and convenience. Its slim, lightweight construction integrates seamlessly with Tech-Air® Ready garments as well as standard leather and textile motorcycle jackets, making it the ideal upgrade for any rider's existing kit. The fully self-contained design eliminates the need for external sensors, tethers, or complicated connections, simply wear it and ride with confidence.
At the heart of the system lies Alpinestars' advanced crash detection algorithm, refined through millions of kilometres of real-world data and rigorous testing. This intelligent technology continuously monitors your riding dynamics and can anticipate impacts, deploying the airbag in just 50 milliseconds, fast enough to provide protection before the moment of impact. Proven effective in direct collision scenarios at speeds between 25–63 km/h, the Tech-Air® 3 V2 offers genuine first-impact protection that could make all the difference when it matters most.

TECH-AIR® 3 MEASUREMENT METHOD
Please take chest measurement, based on how you plan to wear the System. Once you have taken the measurement, consult the size guide below to determine the correct size for your Tech-Air® 3 System.
1. FOR WEARING OVER AN ALPINESTARS JACKET
If you already own an Alpinestars jacket and you plan to wear the Tech-Air® 3 on the outside of the jacket, the recommended size for your Tech-Air® 3 System should be the exact size of the Alpinestars jacket that you plan to wear underneath the Tech-Air® 3 System. For example, if you wear a size L New Waterproof Hoodie, then the correct Tech-Air® 3 size for you should be a size L.
2. MEASUREMENT FOR WEARING OVER THE JACKET
If you plan to wear the Tech-Air® 3 on the outside of the jacket, then you need to take measurement "A" while wearing the jacket.

WARNING
• Tech-Air® 3 in size "S" or below must not in any case be worn under a protective outer garment.

(Providing 4cm of space around the circumference of the upper body to accommodate the Airbag inflation or using the formula described in p23 of the manual.)
Tech-Air® 3 in sizes “M” or larger shall be worn with a Tech-Air® Ready Alpinestars’ outer garment of the same size of the System or with any Alpinestars’ outer garment that is not Tech-Air® Ready provided that the size of the Alpinestars’ outer garment is one size larger than the size of the System or regardless of whether it is an Alpinestars’ outer garment or not meets the following criteria:
* The Tech-Air® 3 System must ALWAYS be used with a properly fitting outer garment to the user’s appropriate body size. Use of the System inside an incorrectly sized outer garment, or with an outer garment that is not compliant with the size check recommendations above, may result in the System malfunctioning or failure and injury, including severe injury and/or death.
