New chapter of the project of “Smart Dress”By Dainese where protection exists but is not perceived by the user who wears it: it is activated only when needed. “The Intelligent Dress – explains Vittorio Cafaggi Ceo D-Air Lab (born in 2015 from the entrepreneurial dream of Lino Dainese, founder of Dainese in 1972, to realize innovative ideas in the most disparate sectors) – combines the ability to control the air by directing it only where it is needed. And then, thanks to the intelligence of the algorithms the suit is able to understand when it is the right moment to activate, that is to warm up or to push away the body humidity “.
Here is the wearable airbag will save the elderly from falls

The new Antartica suit for the most extreme excursions
So after the famous “WorkAir“(The airbag designed to protect workers at height, the first airbag in the world certified as Dpi for the protection of workers from falling), the”D-One“(The dress that makes solitary runs safer in isolated places initially designed for running in urban contexts, at times dangerous, and then extended to the world of cycling and mountain running), the”Future Age”(The airbag that protects the elderly and people with mobility difficulties from possible falls), here is Antarctica, the suit designed to protect explorers and scholars in the most hostile environments.
An intelligent suit that, like the other suits, uses MotoGP technology (with airbags that open in 40 milliseconds, less than the blink of an eye) and that thanks to the collaboration between D-Air Lab and Unless – a non-profit agency founded by Giulia Foscari, dedicated to interdisciplinary research on extreme territories – offers a technologically advanced suit, understood as micro-architecture, able to offer greater autonomy to polar scientists, facilitating field research. Here, however, there are no airbags, but all the air ‘control’ technology, and the design of garments that ‘hold up’ the opening of airbags without damaging those wearing these devices. Not a small thing.
Dainese, a life-saving vest for runners

“The intent with which the Antarctica suit was designed – explains Cafaggi – is to be a” second home “for explorers and scholars, capable of effectively protect them in extreme environmental conditions without compromising their freedom of movement. The Antarctica suit, in fact, is able to maintain a constant body temperature in climatic conditions that reach up to -80 ° C. This is guaranteed by the structure of the suit itself, which is composed of two main layers: an undersuit in contact with the body and a cover in contact with the external environment. With electric resistances, threads intertwined in the weft, which light up to generate heat and eliminate the humidity that lurks under the suit “.

In short, we are faced with a kind of composite suit because the undersuit has been designed to be elastic and adhere to the body with minimum thickness. “In particular – continues the manager of D-Air Lab – was conceived following the logic of regulation of the human body’s own temperature: this first layer, in fact, is made thanks to the intertwining of various yarns, each with specific properties that allow you to adjust the temperature and ventilation / transpiration based on the climatic conditions and their change. Silk allows the undersuit to be comfortable in contact with the skin; the yarn with Tpu (thermoplastic polyurethane) promotes ventilation / transpiration; and the silver yarn makes it possible to create conductive paths capable of conducting heat: the yarns are in fact powered by cold-resistant batteries and, through a flexible PCB positioned in the lumbar area, receive data from sensors located along the body and are activated in case of need. The ventilation is guaranteed by “tunnels” with “C” section obtained thanks to the thermosensitive properties of the Tpu yarns, molded by heat and pressure: the “tunnels” constantly in contact with the body, allow the air to be conveyed outside of the body by evacuating excess moisture “.
And then there is the heart of the project. The external cover: given that the wearer will have to face cold and wind (which in an extreme environment such as Antarctica can reach up to 327 km / h), the suit is obtained from a layering of six different materials, each with specific properties capable of guaranteeing maximum thermal protection. The layers closest to the body retain heat and allow moisture to move outside while the outermost layers keep the cold and wind away. All this by reducing the overall dimensions to a minimum, so as to allow and facilitate every movement.
The undersuit and the outer cover have been designed in such a way as to minimize seams and cuts, with the aim of making the garment light and reliable over time and maximizing freedom of movement. In addition, the Antarctica suit features a flexible display designed to provide essential information to the wearer, such as heart rate, body temperature, excursion time, outside temperature and GPS coordinates. This information comes from the sensors of the undersuit and geolocation devices and are extremely valuable when operating in extreme environments such as Antarctica. The price? When it is marketed, that is, next year, it will cost around 2000 euros.
