Tech-Air 3 v2 Leather Vest

Alpinestars Tech-Air 3 v2 Leather Vest

The Tech-Air 3 v2 Leather brings electronic chest and back protection to a classic black leather riding vest. Its softened leather chassis suits cruiser, touring and everyday road riders who want an airbag layer with traditional styling.

Self-Contained Airbag Protection

• No motorcycle tether or external bike sensors are required.
• Six onboard sensors feed Alpinestars' crash-detection algorithm.
• When inflated, the airbag provides full-chest and full-back Level 2 impact attenuation and Category II PPE certification.
• The magnetic zipper activates the system, with an LED display and vibration feedback for operating status and low-battery alerts.

Leather Construction and Storage

Softened leather and elasticated side panels balance a substantial feel with movement and expansion space. Two zippered hand pockets, two chest pockets and an inside pocket provide storage, with a sunglasses pocket and waist glove loop for riding essentials. The back-protector pocket accepts an optional passive protector. Sealed electronics protect the control unit from weather; the leather vest is not a substitute for rain gear.

Battery and Tech-Air App

The rechargeable battery offers up to 40 hours of use and takes approximately four hours to charge fully. Bluetooth connectivity supports system monitoring and software updates through the Tech-Air App.

Size Chart and Layering

Measure chest circumference with a level tape. For over-jacket wear, measure over your riding jacket. For permitted under-jacket wear, measure over a base layer. These are Alpinestars' Tech-Air 3 size-guide measurements in centimeters.

X-Small and Small: wear over your protective jacket, as directed by the size guide linked to this model. For larger sizes worn underneath, the outer jacket must pass the manufacturer's expansion-clearance check. A jacket that merely zips closed is not necessarily compatible. Check the supplied manual and try the complete riding outfit together.

What Has Improved in V2

V2 supports Alpinestars' replaceable gas-inflator kit, including compatibility with model codes 6505125 and 6505225. User replacement is permitted only in authorized countries and under the kit's instructions; confirm eligibility in the Tech-Air App. After any deployment, inspect the system and follow the required service procedure before riding again.

Setup and Ongoing Care

Complete the manual's first-use setup, verify system readiness before every ride and keep the firmware current. Arrange professional inspection at least every two years or 500 operating hours. This street-riding airbag supplements appropriate motorcycle clothing; it cannot protect against every crash or injury.

Leather Care

The leather vest is not washable. Wipe it with a damp cloth and follow the supplied manual for cleaning, storage and maintenance. Do not immerse the airbag system or apply unapproved cleaning products.
