Lazer Road Z1 MIPS cycling helmet Think about your current helmet; now imagine it lighter, with a more comfortable adjustment system, better ventilation, an additional (optional) aeroshell and improved side impact protection. That's what the Lazer Z1 has to offer. Building on a long tradition of innovation, Lazer decided to combine all the components of a high-performance helmet and develop every feature to the max. This is one of the lightest helmets Lazer has ever made, without compromising on style, safety and comfort. In terms of style, it has the looks of a contemporary, high-performance road helmet with an integrated wing on top. An extra to this helmet is the MIPS system, this is a brain protection system. It is designed to provide extra protection.
