Smith makes their debut into the world of ultra-light full-face helmets with the all-new Mainline MIPS. Featuring extensive ventilation and lightweight yet tough construction, this helmet offers the airy feel of a half-shell while providing downhill-certified coverage for a boost of confidence on rowdy trails. Advanced protective features include Smith's unique Koroyd crumple zones that go above and beyond to disperse impact forces, as well as a MIPS protective layer that helps mitigate harmful oblique impacts.
