Despite its full-face coverage, the Mainline is designed to remain lightweight, breathable, and comfortable for long days on the trail. A network of 21 vents works with Smiths AirEvac ventilation system to promote airflow and help keep goggles fog-free while climbing or charging into descents. The helmet is built for seamless integration with Smith goggles, providing a secure fit and clear vision when riding fast and technical terrain.

Multiple cheek pads, crown liners, and neck rolls allow riders to fine-tune the fit for maximum comfort and stability, while the adjustable visor and classic D-ring chin strap ensure secure performance when the trail gets rough.
