The Smart Jacket utilizes the third-generation D-air Road range technology which includes a 25-hour battery life, plus fast charging capability while allowing maximum airflow thanks to the design of the front portion of the Shield. The unit is folded in half prior to deployment, which permits plenty of air to flow to the rider’s body. Once the Shield is deployed, it envelops the rider’s upper body in a split second and Dainese claims the back of the airbag provides the same amount of impact protection as seven Level 1 back protectors. It can also be repacked at any authorized Dainese dealer.
