Our super lightweight and versatile helmet now weighs even less. The two-part construction of the redesigned Vapor helmet consists of an outer shell made of polycarbonate and a molded layer of super lightweight ALUULA composite material for added protection and reduced weight. The side area with EPP foam provides ventilation and features a sleek aesthetic. The ultra-light cord system allows for easy fine-tuning of the fit. The narrow and interchangeable headlamp clips make the helmet suitable for use after dark.
