Silas is well-ventilated with 24 vents to guide air over and through the bike helmet, evaporate sweat, and cool you down as you ride. What's more, we put this cycling helmet through rigorous safety tests at a CPSC and EN lab and added a safety LED helmet light, to stay seen and safe on the bike path. Silas is engineered to protect and empower you with the peace of mind of having selected the best value bike helmet around. Review: Fantastic Bike Helmet - Five Stars!
