Mainline MIPS Helmet

Credit where credit is due. Thank your mom, your legs, and your team for giving you the chance to clear that rocky gap. Built to go big, fast, or both, the Smith Mainline is our top-tier, downhill-certified enduro helmet. Safety innovations like KOROYD™ and Mips® provide energy-absorbing impact protection, giving you the confidence to charge hard on the trail. Whether you're crushing the EWS in Whistler or suffering through the final stage of your local enduro race, you need a breathable, lightweight helmet that integrates well with goggles and fits like a glove.
