Designed from the Synthe helmet, the Aether is made for road cyclists who want an aerodynamic, efficient and lightweight helmet with an aggressive style. It's the perfect choice for racers and riders looking to exceed their limits. What's more, the Aether offers excellent ventilation to avoid overheating on hot days, allowing you tobe more efficient. A great aero performance allows for free speed gains. The optimized compact shape of the helmet crosses the air regardless of wind angle and head position. Moreover, even if it is aerodynamic, the Aether is better ventilated than the Synthe helmet. The Roc Loc Air adjustment system with two-way adjustment and aero mesh panels with a port is specifically designed to receive your sunglasses and keep them in place when you ride. With the MIPS system, the Aether offers excellent protection against side impacts. Indeed, MIPS system mitigates side shocks by dispersing the impact on a larger area. This avoids having only one point of impact. Also, the Aether has a dual density EPS foam liner to handle a wide range of impacts. That said, the two technologies together will protect the rider.
