Mainline MIPS Helmet

The Smith Mainline downhill-certified enduro bike helmet is fine-tuned for comfort and safety. It doesn't matter if you're slaying the EWS in Whistler or suffering through the last stage of your local enduro race, you need a breathable, lightweight helmet that pairs well with goggles and fits like a glove. 

Speaking of your goggles, fog is not your friend, and this helmet is crafted to integrate with your bike goggles for efficient venting and fog-free vision.

Because Smith wanted to make the best full-face enduro helmet on the market, it includes complete Koroyd® coverage and MIPS Brain Protection System.

Koroyd ® - Unlike traditional protection systems, Koroyd uses crumple zone cylinders that crush uniformly on impact. These absorb and convert more kinetic energy than traditional EPS foam while increasing airflow and reducing overall weight.

MIPS Brain Protection System (BPS) is found inside the helmet, generally between the comfort padding and the EPS. This low friction layer can reduce harmful forces transmitted to the brain by letting the helmet slide relative to the head on certain angled impacts.
