Giant Rev CPSC / CE Helmet - M (18852)

AS NEW! - Never been worn - 55 to 59cm Internal Structural Shell: - A continuous internal polycarbonate shell fuses the helmet structure together. The result is increased overall strength and toughness, and reduced overall weight.  In-mold Micro shell/eps Construction: - The most advanced construction process is used to ensure consistent, seamless materials throughout the helmet for optimal protection and a flawless look. Five outer in-mold micro shells combine with a single, continuous internal shell to provide all-in-one construction for maximum structural integrity. Airflow Ventilation: - A 21-vent cooling system enhanced by a large center vent. The size and shape of the vents helps guide airflow through interior channels to maximize ventilation at low and high speeds for better cooling on climbs or descents.
