Smith Mainline MIPS Helmet

While it is ASTM F1952 downhill certified for maximum protection, the Mainline is surprisingly lightweight at 770 grams. Its 21 vents provide enough airflow to make it a viable option for enduro riding or long days in the bike park where you need full-face coverage without feeling weighed down.

The AirEvac system is designed to pull warm, moist air away from your goggles and exhaust it out the back of the helmet. By aligning the helmet's internal channels with the vents on your goggles, it prevents the stagnant air buildup that typically causes fogging during intense efforts.

Yes, the helmet comes with multiple customizable pad kits. You can swap out the cheek pads, crown liners, and neck rolls to fine-tune the fit to your specific head shape and ensure it stays secure on technical descents.

Koroyd is a honeycomb-like structure that absorbs energy more efficiently than traditional EPS foam upon impact. It allows for a thinner, lighter profile while maintaining high safety standards and significantly increasing airflow through the helmet.

The Mainline uses a D-ring closure system. This is the industry standard for downhill helmets because it provides a secure, reliable fit that won't accidentally release during a crash.

Yes, the visor is adjustable. This allows you to tilt it up or down to accommodate different goggle positions or to block out the sun depending on the trail conditions.
