Black Diamonds superlight, go-anywhere helmet got even lighter. The updated Vapor helmet’s two-piece construction contains a layer of super-light ALUULA composite under the polycarbonate crown for added protection and reduced weight. Molded EPP foam makes up the sides, providing ample venting with the same sleek aesthetic. An ultralight cord fit system makes adjustments and fit easy to fine-tune. Streamlined (and replaceable) headlamp clips are ready for alpine starts or after-dark raps.
