Airbag Vests
| Full Upper-Body Airbag Coverage | One airbag covers the chest, ribs, back and shoulders. |
| Integrated Plasma Back Protector | Alpinestars' Nucleon Plasma impact-absorbing material sits in the back, contoured around the electronics case so the vest stays slim under a jacket. |
| Slim Stretch-Mesh Chassis | A single-layer stretch mesh with a moisture-wicking treatment, shaped to the airbag, and laid out to line up with the ventilation channels in Alpinestars jackets. |
| Riding Modes | Alpinestars list dedicated modes including Street and Race. Holding the system button for two seconds changes mode, a vibration confirms it, and a green LED shows the mode in use. |
| Turns Itself On With The Zip | The system switches on when the activation zip is closed all the way to the top, with a vibration to confirm. |
| Battery | Alpinestars state up to 30 hours of riding per charge. |
| User-Replaceable Canister | A single gas canister sits behind a quick-release service cover. After a deployment the canister can be replaced by the rider where the law allows; Alpinestars sell the replacement canister separately. They state the airbag is certified for six deployments before it must be replaced. |

Description:Alpinestars Tech-Air 5 Plasma Airbag Vest – Black
Product Overview
The Tech-Air 5 Plasma is Alpinestars’ under-jacket airbag system for road, dirt and track riding. It is a self-contained vest worn under your own jacket, with no sensors to fit to the motorcycle.
Alpinestars state the airbag covers the chest, ribs, back and shoulders, and that the system weighs about 1,530 g, which they describe as more than 25% lighter than the earlier Tech-Air 5. A Nucleon Plasma back protector is built into the back of the vest.
