• The Mainframe helmet from Icon was designed with the rider's safety, fit and function in mind
• The shell is constructed of a fiberglass/dyneema blend and is lined with a dual density styrene liner for incredible strength without unnecessary weight
• Features include a Venturi super-vent system for the ultimate in airflow
• A three forehead switch acts as an additional ram-air vent to significantly increase the overall cooling of the helmet
• Internal on/off chin exhaust switch offers control of escaping air

The second coming of the Domain helmet features everything the original Domain has to offer-a light weight composite shell, multiple ram air ducts, fully removable comfort interior, and a fog free quick change shield-but goes one step further by including our new Proshield system. With a shield lock and sideplates, the Proshield is ready to keep you locked down and looking good. Function and fashion-that's the way we do it.

This is the coolest new helmet graphic you'll see from any helmet company all year! Icon's lightest most technologically advanced helmet. The Mechanica graphic features an erotic, robotic woman on both sides with her metallic face on the back. And what better color to put her image on top of than a silver chrome shell? And top it all off with the helmet interior is printed like a circuit board. Everyone wants a helmet that looks great so, what better way to make a helmet look better than putting a chrome shield on a chrome helmet? Icon, at their charitable best, have included a free chrome reflective shield in the box with every Mechanica helmet.
