“Cobbles fly at the Minimum Crag in Utah’s Maple Canyon,” reported one tester, “but most climbers don’t wear a helmet for fear of losing style points and because it gets hot. But the Vapor is so light and low-profile, I kept it on climbing and belaying.” The Vapor has a featherlight expandedpolystyrene (EPS) foam body layered under a polycarbonate shell, with a sheet of puncture-resistant Kevlar as well as carbon rods in between the plastic and the foam. This creates a fully CE-certified helmet at the scant weight of 6.6 ounces—even with a fully adjustable, rigid suspension system. That system completely tucks away to take up less space in the pack, a feature that all testers loved. With 20 vents, testers felt it was too exposed for ice or alpine climbing, but sport and trad climbers loved it for warm-weather sending.
