MET Estro Road Helmet 2014

Whether it is the deep air intake vents in front, the maxi rear vents, the extended lateral lines; every single detail of Estro’s design shows just how much effort has gone into creating a helmet which is both well-ventilated and extremely aerodynamic. The shell of the Estro has depressions which are used to positively modify drag force by influencing the behaviour of the boundary layer (interface zone between the helmet and the air around it), a fundamentally important aspect of aerodynamics

The silhouette of theEstro beginning with its streamlined front which seems to be reaching for the finishing line illustrates the close link it has with the road

MET has its own measurement protocol called Air Scale to monitor how well the helmet’s air cooling system performs by measuring two fundamental parameters: The HCS - the helmet’s contact surface with the head (the less the contact area the better the ventilation) and the helmet’s general capacity to keep the head cool, (the higher the value of the cooling coefficient - the CF - the better the ventilation will be)

Occasionally, without notice, manufacturers change product design and/or specifications.
