Thanks to the many hours dedicated to aerodynamic studies & wind tunnel tests, the special shape of the Y.100 allows for a relatively lightweight helmet with a sporty design that optimizes both stability & soundproofing at high speed. The Y.100R features a double blade air spoiler at the rear that optimizes aerodynamic performance & reduces turbulence at high speeds. The large upper vent & the extremely efficient chin ventilation system allow a large amount of cooling air to enter the helmet. The double EPS liner has an innovative air chamber: this enables a truly breathable helmet with optimum exchange of warm, moist air for cool, fresh air.
