Before wearing Smart Jacket for the first time, you need to install the D-air® software on your computer and register the product by following the instructions. The battery must also be 100% charged to unlock the D-air® system.

Once you receive an email from Dainese confirming correct registration, you can start using the product right away. 

If you do not receive a confirmation email, check your spam folder or contact Dainese technical support.

The D-air® software is available free of charge for Windows and Mac OS operating systems. You can access the page where you can download it directly, using this link.

No, Smart Jacket is completely autonomous and no connection to the motorcycle or other electronic device is necessary. Smart Jacket operation is guaranteed by the electronic control unit on its D-air® system, which is completely independent and self-sufficient and doesn’t need to be connected to anything.

You can wear Smart Jacket over or under any jacket. To choose the correct size, refer to the size guide available on the product page, taking into consideration your preferred usage (under or over the garment).

If you own a two-piece leather suit and want to use it on the road in combination with Smart Jacket, you can wear Smart Jacket over it only if the suit has no aerodynamic hump. If, on the other hand, you prefer a two-piece suit with an integrated airbag system, click here to discover the options available in the D-air® Racing range.

No, Smart Jacket is not compatible with one-piece leather suits. If you are looking for an integrated airbag solution specific to one-piece suits, discover all the options available in the D-air® Racing range.

Once the software is installed on the PC, the data can be downloaded from the suit using a USB cable. The complete software user’s manual can be downloaded from the same 2D website via the above-mentioned link.

This software is related only to the acquisition of data from the suit to the PC. The firmware managing the airbag activation has been installed directly in the suit and can be updated only by Dainese.

Smart Jacket offers outstanding protection due to its D-air® airbag system, equivalent to that of seven back protectors, without the bulk and stiffness of hardshell protective gear. However, if you prefer to wear additional protection such as chest or back protectors, you can do so without any issues.

Yes, you can safely wear a backpack over Smart Jacket.

We only recommend that you be mindful about the objects in the backpack and check that there are no sharp or rigid elements that may compromise the integrity of the airbag in the event of activation.

Smart Jacket is specifically designed for road use with motorcycles and scooters. The control unit of the D-air® system analyzes and monitors what is happening 1000 times per second and autonomously recognizes dangerous situations for a rider during daily road riding in real time.

However, it is not suitable for an exclusive use on the track, where a system with dedicated parameters is preferable (for example D-air® Racing), nor in off-road riding mode.

Smart Jacket is discouraged for off-road riding or on trails with frequent jumps, strong vibrations and intense jolting. In these conditions the D-air® system may mistakenly interpret strong accelerations and sudden movements as dangerous situations and inadvertently activate the airbag. 

Yes, Smart Jacket can also be used with electric motorcycles. In this case, the D-air® system activates automatically as soon as the motorcycle exceeds a speed of 10 km/h, guaranteeing you maximum protection on every journey.

The Smart Jacket system automatically becomes operational when you exceed 10 km/h. Below this speed, the system remains in standby mode.

Yes, the Smart Jacket D-air® system is able to recognize the risk of a rear-end collision when the motorcycle is stationary (for example at a stop sign or at traffic lights), and immediately activate the airbag to protect the motorcycle rider.

Please note:

With conventional motorcycles, the airbag system detects danger and activates if it exceeds 10 km/h and remains operational even when the motorcycle is stationary, sensing the engine vibrations. In the case of an electric motorcycle, on the other hand, Smart Jacket’s D-air® system becomes operational only after exceeding a speed of 10 km/h.

Owing to the sophisticated D-air® algorithm, Smart Jacket immediately activates the airbag in the following situations:

• Impact or collision with objects or vehicles.
• Sliding (with or without rolling).
• High side of motorcycle rider.
• Rear-end collision with stationary motorcycle (at stop sign, traffic lights, intersections, queues).

It means that the airbag ensures timely and effective protection in any road hazard scenario.

To transport Smart Jacket safely, you need to activate Shipping Modefrom the D-air® software. In the case of air travel, we recommend that you contact the airline in advance to check the necessary documentation and transport arrangements for airbag devices. It will probably need to be carried in your checked luggage.

The need to replace or repair Smart Jacket depends on the extent of the damage sustained as a result of the fall. To assess the damage, and if in doubt, contact a specialized Dainese technician at the authorized D-air® sales outlet nearest you.

After one/each airbag activation, it is necessary to replace the bag at a Dainese sales outlet/authorized center, or you can purchase the service online.

When activated, the Smart Jacket airbag remains inflated at maximum pressure for more than/approximately five seconds, ensuring maximum protection throughout the entire fall. After the five seconds, the airbag pressure begins to decrease until it is completely deflated, allowing you to regain mobility and remove the jacket if required.

Recharging Smart Jacket is simple: Turn off the device and connect it to a computer or a regular power outlet with the USB-C cable provided in the box. A full charge (from 0 to 100%) takes approximately four hours and allows Smart Jacket to provide over 26 hours of continuous use in active mode.

To turn off Smart Jacket, simply unfasten the vest fastening buttons. We recommend you verify that the system is actually off using the LED indicator.

Dainese recommends servicing the D-Air system after the first three years from the date of purchase. The inspection is free of charge and can be carried out directly at one of our Dainese stores or D-Air Premium Center retailers. You can find the nearest store at the following link – we suggest selecting the "D-Air Premium Center" filter among the available services: Store Locator. We recommend calling the store before your visit.

If any repairs are needed, you will be provided with a cost estimate.

Once you have registered your Smart Jacket after purchase, you will receive periodic email communications telling you when you need to update the software.

For routine Smart Jacket cleaning, use a damp cloth, gently rubbing it over the surface of the vest. Avoid using harsh detergents, machine washing or immersion in water, to preserve the integrity of the system.

Smart Jacket is covered by official warranty. The duration varies according to your country’s existing legislation.

We recommend that you check the specific conditions for your area.

Smart Jacket weighs approximately 1.8 kg, lower than the average motorcycle jacket with certified hard protectors, to ensure greater lightness and comfort. 

Smart Jacket is a ventilated garment, designed to be as light and unobtrusive as possible. Its fabric is water-repellent but not waterproof, so it doesn't off protection against rain.

If the D-AIR STREET SMART JKT is integrated into a NON-waterproof garment, you must protect the system from rain with a rain jacket worn over it.

Smart Jacket is made of certified abrasion-resistant and tear-resistant fabric. In the event of a slide, both the material and the D-air® airbag protect against abrasions and scratches in the areas covered by the vest, ensuring greater safety.
