Combining maximum comfort with the benefits of excellent temperature regulation, the third generation of the Prevail is the ultimate all-around helmet that excels in hot conditions, strenuous climbs and mountain stages. To accomplish this, engineers removed the airflow-blocking foam bridges in the center of the helmet, making the Prevail 3 the Specialized helmet with the largest ventilation area (24.5 % larger than the Prevail II Vent's).
