Built on the same core design principles as the pro-level Z20, the Stratus combines lightweight aerodynamic efficiency with cutting-edge comfort technologies. The shape was refined for all-road performance, vented for long climbs but still fast for flats, and the integrated Float Fit system offers comfort and safety with a streamlined fit and an oversized dial that is easy to adjust with one hand. The Overbrow ventilation system draws cold air through the front and pushes it through an air channel matrix to reduce overheating. And thanks to the twist-free adjustable Tri-Glides, the straps stay flat and properly positioned no matter how hard you're hammering. This model also includes MIPS (Multi-Directional Impact Protection System) for added protection in certain types of impacts. Integrated MIPS (Multi-Directional Impact Protection System): MIPS is designed to reduce rotational forces that can result from certain impacts. By integrating the MIPS sliding plane into the retention system, we are able to reduce complexity and weight for a compact, better ventilated helmet that fits more closely to the head.
