SMITH Mainline Mips Helmet

Yes, the Mainline Mips is certified to the NTA8776 standard, which is specifically designed for the higher speeds and impact requirements of e-bikes, in addition to standard downhill and bicycle certifications.

The helmet is designed to align with Smith goggles to create a continuous airflow path. It pulls warm, moist air away from your goggles and out through the helmet's 21 vents, preventing the buildup that causes fogging during high-exertion rides.

Absolutely. The helmet comes with multiple sets of removable liners and cheek pads of varying thicknesses, allowing you to customize the internal fit to match your specific head shape and comfort preferences.

At 770 grams, it is relatively lightweight for a full-face helmet. While it is built for the rigors of downhill racing, the weight is balanced well enough that it remains comfortable for long days of enduro riding without causing excessive neck fatigue.

The D-ring closure is a standard for downhill and enduro racing because it provides the most secure and precise fit. While it takes a moment longer to fasten than a buckle, it ensures the helmet stays firmly in place during aggressive riding.

The Mainline is engineered for seamless integration with Smith performance goggles, but the wide eyeport is designed to accommodate most modern mountain bike goggles. If you use a different brand, they will likely fit, but you may lose some of the specific ventilation benefits of the AirEvac system.
