Black Diamond Vapor Helmet, the most lightweight, breathable and comfortable of all the helmets ever designed by Black Diamond, the Vapor offers protection which is both ultra lightweight and extremely reliable. The Vapor helmet by Black Diamond weighs a mere 186 g; an ultra lightweight helmet, featuring ample air vents and a padded suspension system which is completely adjustable. The Vapor is the lightest, most comfortable and breathable climbing helmet ever produced by Black D. Combining feather light, unencumbered and well ventilated protection for the head with secure and comfortable adjustability, the Vapor by Black Diamond is an all-purpose climbing helmet which proves that helmets are not only useful for lengthy ascents or the highest mountain peaks. Black Diamond have inserted a Kevlar sheet and a series of carbon rods between the molded EPS foam and the polycarbonate shell to lighten the weight as much as possible without compromising on the effectiveness of the protection offered. The ratcheting suspension system of the Vapor folds into the helmet for compact storage in the bag. The removable headlamp clips are reliable enough to hold your lamp firmly in place during pre-dawn and after-dusk excursions.
