Its open-face design prioritizes comfort with a snug fit for intermediate oval head shapes, though ventilation is minimal, offering limited airflow for warmer conditions. Safety tech includes a DOT certification, ensuring compliance with basic safety standards, but lacks advanced features like MIPS or multi-density foam.
