Fusion In-Mold Microshell with Internal Reinforcement offers protection, durability and impact resistance for whatever you might encounter on the trail. 18 whopping vents bring cool air in through the front, allowing it to pass over your head and then flushes warm air out of the rear ports – so YOU stay cool and your HEAD stays cool. Blade visor easily snaps into place to protect your eyes from the sun, rain and any other airborne items. One handed, GPS Fit System keeps your helmet secure through the technical sections.
