A team of professionals to prove D-air effectiveness after Matthias Mayer's crash


Medical experts, ÖSV, FIS and Dainese together to prove D-air effectiveness after Matthias Mayer's crash on Saslong course.


After Matthias Mayer’s fall occurred in Gröden during the Ski Downhill race on Saslong course, a group of experts met at ȌSV headquarters to deeply analyze the crash event.


The meeting was attended by medical staff - Dr. Christian Haid, Ass. Prof. at the Innsbruck Orthopedics University Clinic, Director of the Biomechanics Laboratory and Dr. Michael Gabl, Medical Director of the Spine Centre of Sanatorium Kettenbruecke based in Innsbruck - ȌSV representatives and Dainese technicians.


Telemetry provided by Dainese was related to images and assessments of Dr. Christian Haid and Dr. Michael Gabl, the neurosurgeon that took care of and operated on Matthias Mayer. Both the dynamics of the fall and the system worn by Mayer were carefully analyzed together with Dainese’s technicians, examining the data collected by D-air® Ski’s accelerometers and gyroscopes, and the circumstances and consequences of the accident.


Experts firmly state that Mayer’s injuries are the outcome of the several forces’ combination (compression, rotation and bending), taking into consideration that the fall took place at extremely high speed. The back protector and the electronics were fully intact.


Dr. Gabl confirmed that “the D-air® Ski has most probably prevented the athlete to report further thoracic injuries”.


Dainese presented the data collected during the fall, pointing out that the collision with the ground took place at a speed of 109 km/h , generating accelerations up to 13G and consequent multiple hard impacts on the slope.


Günther Hujara, FIS Technical Expert who firstly assisted the athlete after the crash, stated: “A very serious investigation of the crash of Matthias Mayer was undertaken by the Austrian Ski Association and Dainese with the University of Innsbruck. The Medical Expertise and the Biomechanical Expertise have also shown that the D-air® Ski worked properly and that no parts of the D-air® Ski”, specifically the back protector, “could cause those injuries”. Hujara also added that “as in the past, FIS will continue to support the future development of the D-air® system to improve safety of the athletes”.


After intensive discussion in between the experts, ȌSV concluded that today there is no reason to limit the use of the D-air® Ski for their athletes of speed disciplines and agreed with Dainese to further foster the technical development of this innovative protective system.


More than 1000 deployments during test sessions on the slopes, in the Moto GP World Championship and on open roads, all together prove the effectiveness of the D-air® technology.


The D-air® platform represents the state of the art in protection technology applied to dynamic sports and embodies Dainese's mission to make its practice even safer.


The future of protection is in D-air®.
