Whether you're clipping bolts in Utah's Maple Canyon or navigating through seldom-traveled trad pitches, strap on the ultralight Black Diamond Vapor Helmet for tough head protection. The low-profile design and featherlight weight of under seven ounces make it easy to forget you're even wearing a helmet. Plus, the geometric vents provide ample air-flow for hot summer days at the crag, so you don't have to wait for send temps to finish your project.
