Petzl's Vertex Vent Helmet
Petzl’s Vertex Vent helmet has a six-point suspension system designed to keep the helmet shell positioned above the user’s head, which in conjunction with the openable side vents allows for breathability. The CenterFit adjustment keeps the helmet centered on the user’s head. It is designed to accommodate accessories like a headlamp, protective shield and hearing protection. A non-vent version is available for those needing electrical insulation or molten metal spray protection.
