The men’s Anon Prime helmet offers the ultimate in safety features, light weight, and performance. It boasts the In-Shell 360° Boa® Fit System for easy, on-the-go fit adjustment with the turn of a dial. The Hybrid 50/50 shell construction combines durability on top with the performance of a featherweight bottom for a helmet that is incredibly light yet tough. The MIPS (Multidirectional Impact Protection System) offers the safest protection against angled impacts, while ICEdot Emergency ID stores emergency contact and medical information for first responders. Adjustable ventilation gives you one-handed control over 23 total vents, so you can fine tune your temperature depending on the weather and activity.
