The wide brim One K helmet you've come to love with integrated MIPS technology, which is intended to add protection against rotational impacts to the head that could result from riding accidents at high speeds.
A helmet is only safe, if it fits correctly. It is always better to be fit by a professional than it is to purchase a helmet on line.
Matte polycarbonate and advanced ABS composite outer shell
Comfort padded harness with synthetic suede lining
Wide brim for added sun protection
Two front, one back, and two center stripe vents
Safety standards: certified to ASTM standards.

MIPS (Multi-Directional Impact Protection System) was founded in 1996 by a neurosurgeon and a researcher from the Royal Institute of Technology, both located in Stockholm, Sweden. MIPS is designed to add protection against rotational motion (or kinematics) transmitted to the brain from angled impacts to the head.
Rotational motion is a combination of rotational energy (angular velocity) and rotational forces from angular acceleration that both affect the brain and increase the risk for minor and severe brain injuries. MIPS’ added protection system has been proven to reduce rotational motion when implemented in a helmet by redirecting energies and forces otherwise transmitted to the brain.
One K has embraced MIPS technology in their helmets. The adoption of MIPS provides further protection to reduce brain shear in riding accidents involving falls at speed.
