The Smith Liberty MIPS Helmet is a new hybrid model that takes it's design cues from the Vantage but ups the ante in the style department. With a hard shell top section and in-mold lower, the Liberty uses Aerocore™ construction (Koroyd™ honeycomb) for additional crush resistance with almost no weight increase. Great ventilation is provided by 20 vents and controlled by a low-profile regulator slider, and a VaporFit™ adjustable sizing mechanism allows you to dial in the fit to a "T."
