The Giro Cinder MIPS isn't just a good looking road bike helmet, but boasts some great properties as well. The design is based on the immensely successful Synthe helmet, Giro's top of the line product. The Cinder is built using the so-called In-Mold construction which has a polycarbonate external shell fused to a shock absorbing foam liner on the inside. The addition of the MIPS system makes the Cinder as safe as can be! The Giro Cinder MIPS road bike helmet also has excellent breath ability because of its Wind Tunnel ventilation. Active vents are combined with internal air channels to improve the overal ventilation. The Roc Loc 5 system ensures both the fit and vertical position of the helmet are easily adjusted, ensuring a perfect fit!
