Black Diamond’s superlight, go-anywhere Vapor helmet is now even lighter. The helmet’s two-piece construction contains a layer of super-light ALUULA composite under the polycarbonate crown for added protection and reduced weight. The Vapor's moulded EPP foam on the side makes provides ample venting with the same sleek aesthetic. An ultralight cord fit system makes adjustments easy to fine-tune. Streamlined headlamp clips are ready for alpine starts or after-dark raps. Vapor Climbing Helmet
